$_POST 在 fetch_assoc 中具有相同的名称
$_POST with the same name in a fetch_assoc
大家好
今天我有一个有趣的问题（至少对我来说是这样）。我正在创建 div 和输入
在 fetch_assoc 中，我想知道提交所有这些输入的最佳方式。它们
具有相同的名称，但它们具有不同的值，有时甚至相同。
这是代码：
<?php
$sql = "SELECT IDBewoner, Foto FROM Bewoners LIMIT 5";
$res = mysqli_query($mysqli, $sql);
$totaalbewoners = mysqli_num_rows($res);
while($row = mysqli_fetch_assoc($res)) {
?>
<tr>
<form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="POST">
<td><input type="text" value="<?php echo $row["IDBewoner"] ?>" name="bewoner"></td>
<td> <?php echo $row["IDBewoner"] ?> </td>
<td> <?php echo "<img src='data:image/jpeg;base64,".base64_encode($row['Foto'])."' width='90' height='90'>" ?> </td>
<td>
<div id="rang1" class="DropZone"></div>
<input type="hidden" value="" id="rang1input" name="rang1value" />
</td>
<td>
<div id="rang2" class="DropZone"></div>
<input type="hidden" value="" id="rang2input" name="rang2value" />
</td>
<td>
<div id="rang3" class="DropZone"></div>
<input type="hidden" value="" id="rang3input" name="rang3value" />
</td>
<td>
<div id="rang4" class="DropZone"></div>
<input type="hidden" value="" id="rang4input" name="rang4value" />
</td>
<td>
<div id="rang5" class="DropZone"></div>
<input type="hidden" value="" id="rang5input" name="rang5value" />
</td>
<td>
<div id="rang6" class="DropZone"></div>
<input type="hidden" value="" id="rang6input" name="rang6value" />
</td>
<td>
<div id="rang7" class="DropZone"></div>
<input type="hidden" value="" id="rang7input" name="rang7value" />
</td>
<input type="submit" value="Save">
</form>
</tr>
<?php
if($_SERVER["REQUEST_METHOD"] == "POST") {
/*for($i = 0; $i < $totaalbewoners; $i++) { [!!DANGEROUS CODE!!]
$rang1bewoner.$i = $_POST["rang1value"][$i];
}*/
$rang1 = $_POST["rang1value"];
$rang2 = $_POST["rang2value"];
$rang3 = $_POST["rang3value"];
$rang4 = $_POST["rang4value"];
$rang5 = $_POST["rang5value"];
$rang6 = $_POST["rang6value"];
$rang7 = $_POST["rang7value"];
$bewonerID = $_POST["bewoner"];
/*echo "<script>alert('Bewoner: $bewonerID')</script>";
echo "<script>alert('Rang1: $rang1')</script>";
echo "<script>alert('Rang2: $rang2')</script>";
echo "<script>alert('Rang3: $rang3')</script>";
echo "<script>alert('Rang4: $rang4')</script>";
echo "<script>alert('Rang5: $rang5')</script>";
echo "<script>alert('Rang6: $rang6')</script>";
echo "<script>alert('Rang7: $rang7')</script>";*/
}
}
?>
我首先将 if $_SERVER["METHOD_REQUEST"] 放在 fetch_assoc 下，但只得到了值
第一行的。然后我把它放在 while fetch_assoc 中（正如你在我的代码中看到的那样），但没有用
要么一遍又一遍地得到相同的值。然后我尝试更改输入的名称
到 name="rang6value[]" 然后在 php 代码中我写了 for 使用总行数作为
最大值（您可以在 php 的评论中看到它）并且我的浏览器崩溃了（这很有趣）。
所以现在的问题是：如何以一种简单的方式为
获取输入字段的所有值
所有的行？如果你能帮助我，我的生活会好得多。
非常感谢您。 ^^
更新：插入代码：
<?php
if($_SERVER["REQUEST_METHOD"] == "POST") {
$rang1 = $_POST["rang1value"];
$rang2 = $_POST["rang2value"];
$rang3 = $_POST["rang3value"];
$rang4 = $_POST["rang4value"];
$rang5 = $_POST["rang5value"];
$rang6 = $_POST["rang6value"];
$rang7 = $_POST["rang7value"];
$bewonerID = $_POST["bewoner"];
if(!empty($rang1)) {
$insert1 = "INSERT INTO ActiviteitenSchema
(DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr)
VALUES
(4, '$bewonerID', '$rang1', '2015-04-14', 1)";
$res = $mysqli->query($insert1);
}
if(!empty($rang2)) {
$insert2 = "INSERT INTO ActiviteitenSchema
(DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr)
VALUES
(4, '$bewonerID', '$rang2', '2015-04-14', 2)";
$res = $mysqli->query($insert2);
}
if(!empty($rang3)) {
$insert3 = "INSERT INTO ActiviteitenSchema
(DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr)
VALUES
(4, '$bewonerID', '$rang3', '2015-04-14', 3)";
$res = $mysqli->query($insert3);
}
if(!empty($rang4)) {
$insert4 = "INSERT INTO ActiviteitenSchema
(DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr)
VALUES
(4, '$bewonerID', '$rang4', '2015-04-14', 4)";
$res = $mysqli->query($insert4);
}
if(!empty($rang5)) {
$insert5 = "INSERT INTO ActiviteitenSchema
(DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr)
VALUES
(4, '$bewonerID', '$rang5', '2015-04-14', 5)";
$res = $mysqli->query($insert5);
}
if(!empty($rang6)) {
$insert6 = "INSERT INTO ActiviteitenSchema
(DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr)
VALUES
(4, '$bewonerID', '$rang6', '2015-04-14', 6)";
$res = $mysqli->query($insert6);
}
if(!empty($rang7)) {
$insert7 = "INSERT INTO ActiviteitenSchema
(DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr)
VALUES
(4, '$bewonerID', '$rang7', '2015-04-14', 7)";
$res = $mysqli->query($insert7);
}
}
?>
这是你想要做的吗？
$values = array;
for ($i=1; $i<=7; $i++)
{
$values [$i] = $_POST["rang".$i."value"];
}
如果您想要一个表单，请将表单标签放在 while 循环之外
<?php
$sql = "SELECT IDBewoner, Foto FROM Bewoners LIMIT 5";
$res = mysqli_query($mysqli, $sql);
$totaalbewoners = mysqli_num_rows($res);
?>
<form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="POST">
<?php while($row = mysqli_fetch_assoc($res)) {
?>
<tr>
<td><input type="text" value="<?php echo $row["IDBewoner"] ?>" name="bewoner"></td>
<td> <?php echo $row["IDBewoner"] ?> </td>
<td> <?php echo "<img src='data:image/jpeg;base64,".base64_encode($row['Foto'])."' width='90' height='90'>" ?> </td>
<td>
<div id="rang1" class="DropZone"></div>
<input type="hidden" value="1" name="rang_input[][]" id="rang1value" />
</td>
<td>
<div id="rang2" class="DropZone"></div>
<input type="hidden" value="2" name="rang_input[][]" id="rang2value" />
</td>
<td>
<div id="rang3" class="DropZone"></div>
<input type="hidden" value="3" name="rang_input[][]" id="rang3value" />
</td>
<td>
<div id="rang4" class="DropZone"></div>
<input type="hidden" value="4" name="rang_input[][]" id="rang4value" />
</td>
<td>
<div id="rang5" class="DropZone"></div>
<input type="hidden" value="5" name="rang_input[][]" id="rang5value" />
</td>
<td>
<div id="rang6" class="DropZone"></div>
<input type="hidden" value="6" name="rang_input[][]" id="rang6value" />
</td>
<td>
<div id="rang7" class="DropZone"></div>
<input type="hidden" value="7" name="rang_input[][]" id="rang7value" />
</td>
<?php };?>
<input type="submit" value="Save">
</form>
</tr>
<?php
if($_SERVER["REQUEST_METHOD"] == "POST") {
foreach ($_POST['rang_input'] as $key => $value) {
foreach ($value as $key1 => $value1) {
echo $value1 . "<br />";
}
}
}
?>
那这个怎么样？假设您的输入有 ids own1rang1value、own1rang2value 等
$values = array;
for ($owner=1; $owner<=7; $owner++)
{
$rec = array;
for ($i=1; $i<=7; $i++)
{
$rec [$i] = $_POST["own".$owner."rang".$i."value"];
}
$values[$owner]=$rec;
}
尝试修改您的表单以包含您的 IDBewoner （无论一个好的唯一字段是什么，这个字段可能不是唯一的，我不知道，很难说） 双数组中的值，例如：
<?php
$sql = "SELECT IDBewoner, Foto FROM Bewoners LIMIT 5";
$res = mysqli_query($mysqli, $sql);
$totaalbewoners = mysqli_num_rows($res);
while($row = mysqli_fetch_assoc($res)) {
?>
<tr>
<form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="POST">
<td>
<input type="text" value="<?php echo $row["IDBewoner"] ?>" name="bewoner[]">
</td>
<td>
<?php echo $row["IDBewoner"] ?>
</td>
<td>
<img src="data:image/jpeg;base64,<?php echo base64_encode($row['Foto']); ?>" width='90' height='90'>
</td>
<?php for($i=0; $i <= 7; $i++) {
$owner_id = $i.$row["IDBewoner"]; ?>
<td>
<div id="rang<?php echo $owner_id; ?>" class="DropZone"></div>
<input type="text" value="" id="rang<?php echo $owner_id; ?>input" name="rang[<?php echo $row["IDBewoner"]; ?>][<?php echo $i; ?>]" />
</td>
<?php }
} ?>
<td>
<input type="submit" name="submit" value="submit" />
</td>
</form>
</tr>
会给你一个类似于的数组（我没有填写任何值，所以它们都是空白的）:

这就是您处理 sql 的方式。请注意，您应该清理或绑定值，但我没有包含任何类似的内容：
<?php
if(isset($_POST["submit"])) {
$sql['cols'] = "INSERT INTO `ActiviteitenSchema` (DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr) VALUES";
$i = 0;
foreach($_POST['rang'] as $key => $value) {
$z = 0;
foreach($value as $rang) {
if(!empty($rang)) {
$vals[$i][] = "(4, '".$_POST['bewoner'][$i]."', '".$rang."', '2015-04-14', '$z')";
}
$z++;
}
if(isset($vals[$i]))
$sql['vals'][] = implode(", ",$vals[$i]);
$i++;
}
if(isset($sql['vals'])) {
$statement = $sql['cols'].implode(", ",$sql['vals']);
$res = $mysqli->query($statement);
}
}
?>
插入代码：
<?php
if(isset($_POST["submit"])) {
$sql['cols'] = "INSERT INTO ActiviteitenSchema (DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr) VALUES";
$i = 0;
foreach($_POST['rang'] as $key => $value) {
$z = 0;
foreach($value as $rang) {
if(!empty($rang)) {
$vals[$i][] = "(4, '".$_POST['bewoner'][$i]."', '".$rang."', '2015-04-14', '$z')";
}
$z++;
}
if(isset($vals[$i])) {
$sql['vals'][] = implode(", ",$vals[$i]);
}
$i++;
}
if(isset($sql['vals'])) {
$statement = $sql['cols'].implode(", ",$sql['vals']);
$res = $mysqli->query($statement);
echo "<script>alert('gegevens zijn toegevoegd')</script>";
header("Location: nieuwschema.php");
}
}

我有PHP_SELF的操作，把插入代码放在同一页的底部。
大家好
今天我有一个有趣的问题（至少对我来说是这样）。我正在创建 div 和输入
在 fetch_assoc 中，我想知道提交所有这些输入的最佳方式。它们
具有相同的名称，但它们具有不同的值，有时甚至相同。
这是代码：
<?php
$sql = "SELECT IDBewoner, Foto FROM Bewoners LIMIT 5";
$res = mysqli_query($mysqli, $sql);
$totaalbewoners = mysqli_num_rows($res);
while($row = mysqli_fetch_assoc($res)) {
?>
<tr>
<form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="POST">
<td><input type="text" value="<?php echo $row["IDBewoner"] ?>" name="bewoner"></td>
<td> <?php echo $row["IDBewoner"] ?> </td>
<td> <?php echo "<img src='data:image/jpeg;base64,".base64_encode($row['Foto'])."' width='90' height='90'>" ?> </td>
<td>
<div id="rang1" class="DropZone"></div>
<input type="hidden" value="" id="rang1input" name="rang1value" />
</td>
<td>
<div id="rang2" class="DropZone"></div>
<input type="hidden" value="" id="rang2input" name="rang2value" />
</td>
<td>

<?php
if($_SERVER["REQUEST_METHOD"] == "POST") {
/*for($i = 0; $i < $totaalbewoners; $i++) { [!!DANGEROUS CODE!!]
$rang1bewoner.$i = $_POST["rang1value"][$i];
}*/
$rang1 = $_POST["rang1value"];
$rang2 = $_POST["rang2value"];

$rang4 = $_POST["rang4value"];

echo "<script>alert('Rang7: $rang7')</script>";*/
}
}
?>
我首先将 if $_SERVER["METHOD_REQUEST"] 放在 fetch_assoc 下，但只得到了值
第一行的。然后我把它放在 while fetch_assoc 中（正如你在我的代码中看到的那样），但没有用
要么一遍又一遍地得到相同的值。然后我尝试更改输入的名称
到 name="rang6value[]" 然后在 php 代码中我写了 for 使用总行数作为
最大值（您可以在 php 的评论中看到它）并且我的浏览器崩溃了（这很有趣）。
所以现在的问题是：如何以一种简单的方式为
获取输入字段的所有值
所有的行？如果你能帮助我，我的生活会好得多。
非常感谢您。 ^^
更新：插入代码：

}
?>
这是你想要做的吗？
$values = array;
for ($i=1; $i<=7; $i++)
{
$values [$i] = $_POST["rang".$i."value"];
}
如果您想要一个表单，请将表单标签放在 while 循环之外
<?php
$sql = "SELECT IDBewoner, Foto FROM Bewoners LIMIT 5";
$res = mysqli_query($mysqli, $sql);
$totaalbewoners = mysqli_num_rows($res);
?>
<form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="POST">
<?php while($row = mysqli_fetch_assoc($res)) {
?>
<tr>
<td><input type="text" value="<?php echo $row["IDBewoner"] ?>" name="bewoner"></td>
<td> <?php echo $row["IDBewoner"] ?> </td>

</td>
<?php };?>
<input type="submit" value="Save">
</form>
</tr>
<?php
if($_SERVER["REQUEST_METHOD"] == "POST") {
foreach ($_POST['rang_input'] as $key => $value) {
foreach ($value as $key1 => $value1) {
echo $value1 . "<br />";
}
}
}
?>
那这个怎么样？假设您的输入有 ids own1rang1value、own1rang2value 等
$values = array;
for ($owner=1; $owner<=7; $owner++)
{
$rec = array;
for ($i=1; $i<=7; $i++)
{
$rec [$i] = $_POST["own".$owner."rang".$i."value"];
}
$values[$owner]=$rec;
}
尝试修改您的表单以包含您的 IDBewoner （无论一个好的唯一字段是什么，这个字段可能不是唯一的，我不知道，很难说） 双数组中的值，例如：
<?php
$sql = "SELECT IDBewoner, Foto FROM Bewoners LIMIT 5";
$res = mysqli_query($mysqli, $sql);
$totaalbewoners = mysqli_num_rows($res);
while($row = mysqli_fetch_assoc($res)) {
?>
<tr>
<form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="POST">
<td>
<input type="text" value="<?php echo $row["IDBewoner"] ?>" name="bewoner[]">
</td>
<td>
<?php echo $row["IDBewoner"] ?>
</td>
<td>
<img src="data:image/jpeg;base64,<?php echo base64_encode($row['Foto']); ?>" width='90' height='90'>
</td>
<?php for($i=0; $i <= 7; $i++) {
$owner_id = $i.$row["IDBewoner"]; ?>
<td>
<div id="rang<?php echo $owner_id; ?>" class="DropZone"></div>
<input type="text" value="" id="rang<?php echo $owner_id; ?>input" name="rang[<?php echo $row["IDBewoner"]; ?>][<?php echo $i; ?>]" />
</td>
<?php }
} ?>
<td>
<input type="submit" name="submit" value="submit" />
</td>
</form>
</tr>
会给你一个类似于的数组（我没有填写任何值，所以它们都是空白的）:
Array
(
[bewoner] => Array

这就是您处理 sql 的方式。请注意，您应该清理或绑定值，但我没有包含任何类似的内容：
<?php
if(isset($_POST["submit"])) {
$sql['cols'] = "INSERT INTO `ActiviteitenSchema` (DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr) VALUES";
$i = 0;
foreach($_POST['rang'] as $key => $value) {
$z = 0;
foreach($value as $rang) {
if(!empty($rang)) {
$vals[$i][] = "(4, '".$_POST['bewoner'][$i]."', '".$rang."', '2015-04-14', '$z')";
}
$z++;
}
if(isset($vals[$i]))
$sql['vals'][] = implode(", ",$vals[$i]);
$i++;
}
if(isset($sql['vals'])) {
$statement = $sql['cols'].implode(", ",$sql['vals']);
$res = $mysqli->query($statement);
}
}
?>
插入代码：
<?php
if(isset($_POST["submit"])) {
$sql['cols'] = "INSERT INTO ActiviteitenSchema (DagVanDeWeek, Bewoner, Activiteit, DatumAangemaakt, Rangnr) VALUES";
$i = 0;
foreach($_POST['rang'] as $key => $value) {
$z = 0;
foreach($value as $rang) {
if(!empty($rang)) {
$vals[$i][] = "(4, '".$_POST['bewoner'][$i]."', '".$rang."', '2015-04-14', '$z')";
}
$z++;
}
if(isset($vals[$i])) {
$sql['vals'][] = implode(", ",$vals[$i]);
}
$i++;
}
if(isset($sql['vals'])) {
$statement = $sql['cols'].implode(", ",$sql['vals']);
$res = $mysqli->query($statement);
echo "<script>alert('gegevens zijn toegevoegd')</script>";
header("Location: nieuwschema.php");
}
}
?>
fetch_assoc:
<div id="MainDiv">
<div id="ListBewoners">
<table id="ListBewonersUL">
<?php
$sql = "SELECT IDBewoner, Foto FROM Bewoners LIMIT 5";
$res = mysqli_query($mysqli, $sql);
$totaalbewoners = mysqli_num_rows($res);
while($row = mysqli_fetch_assoc($res)) {
?>
<tr>
<form action="<?php echo $_SERVER["PHP_SELF"] ?>" method="POST">
<td>
<input type="text" value="<?php echo $row["IDBewoner"] ?>" name="bewoner[]" size="2">
</td>
<td>
<?php echo $row["IDBewoner"] ?>
</td>
<td>
<img src="data:image/jpeg;base64,<?php echo base64_encode($row['Foto']); ?>" width='90' height='90'>
</td>
<?php for($i=0; $i < 7; $i++) {
$owner_id = $i.$row["IDBewoner"]; ?>
<td>
<div id="rang<?php echo $owner_id; ?>" class="DropZone"></div>
<input type="text" value="" id="rang<?php echo $owner_id; ?>input" name="rang[<?php echo $row["IDBewoner"]; ?>][<?php echo $i; ?>]" />
</td>
<?php }
} ?>
</tr><tr>
<td>
<input type="submit" name="submit" value="Save" />
</td>
</form>
</tr>
</table>
</div>
</div>
我有PHP_SELF的操作，把插入代码放在同一页的底部。
