在 PHP 中插入 select2 标签 jQuery 数组

Question

我在 Whosebug 上看到了很多关于这个问题的帖子，但我无法做到这一点，所以再次 post。我正在使用 select2 jQuery plugin，我想使用 PHP 在 SQL 中插入标签。喜欢 [Data, Data, Data]

我尝试做我通过 google 学到的东西，我在这方面很专业，我是 PHP 的新手。请帮忙'How I Insert this in DB where show , between two words as above I mentioned in Like'

我的代码是

if(isset($_POST['submit'])) {
    $name = "Your_Name";
    $email = "Your_Email";

    $stmt = $con->prepare("INSERT INTO `test` (`name`, `email`, `color_name`) VALUES (':name',':email',':color')");
    foreach ($data as $row)
    {
        ':name' = $name;
        ':email' = $email;
        ':color' = 'MYStatus'; //I want mention here Select2 Tags Data and insert in DB where [, (space)] every two words. like [Green, Red, Blue, Pink] 
        $stmt->execute();
    }
  }

Answer 1

您的表单很可能是这样发送的：

Array
(
    [selectname] => Array
        (
            [0] => brown,Green,Blue
        )

)

因此，既然您希望将其格式化为 brown, Green, Blue，那么您可以 explode() 和 implode() 或者只使用 str_replace():

# Exploding, imploding
$tags = implode(", ", explode(",", $_POST['selectname'][0]));

# String replace would be
$tags = str_replace(',', ', ', $_POST['selectname'][0]);

如果您尝试拆分该字符串以分别插入每个标签，您可以在逗号上使用 explode()，然后循环 explode().

的结果

我可能会在那里使用 trim() 来删除空的 space，以防万一。另外，如果你想确保它们的格式都相同，你可能想做 ucwords() 以确保每个单词的首字母都是大写 （你的默认值 brown 都是小写的，重置的第一个字母是大写的）.

如果你使用方法 1，你可以应用 ucfirst() 和 trim() 如果你在展开的字符串上使用 array_map()：

# A full combination of functions
$tags = implode(", ", array_map(function($v){
    return ucfirst(trim($v));
}, explode(",", $_POST['selectname'][0])));

会给你字符串：

Brown, Green, Blue

编辑：

由于您实际上是按行存储，因此您可以使用 select:

取回数组

function getColorTags($name, $con)
{
    # Query by name, just return the color_name field though
    $query = $con->prepare("SELECT `color_name` FROM `test` WHERE `name` = ?");
    # Execute the query with bind value
    $query->execute([$name]);
    # Loop the results
    while($result = $query->fetch(\PDO::FETCH_ASSOC)) {
        # Store the tags
        $row[] = $result['color_name'];
    }
    # Return the tags or an empty array
    return (isset($row))? $row : [];
}

使用：

# Fetch the tags by name, make sure to inject the database connection
$tags = getColorTags('Some Name', $con);
# Print out the array
print_r($tags);

要在同一页上同时执行这两个操作，您只需使用 json_encode():

<?php
function insertTags($data, $email, $name, $con)
{
    $stmt = $con->prepare("INSERT INTO `test` (`name`, `email`, `color_name`) VALUES (?,?,?)");

    foreach ($data as $string) {
        # Explode and filter the tags from the js
        $arr = array_filter(array_map('trim', explode(',', $string)));
        # Loop the "selectname"
        foreach($arr as $tag) {
            # Execute all the rows
            $stmt->execute([$name, $email, $tag]);
        }
    }
}
# This fetches using the email as the primary key
function getColorTags($email, $con)
{
    # Query by name, just return the color_name field though
    $query = $con->prepare("SELECT `color_name` FROM `test` WHERE `email` = ?");
    # Execute the query with bind value
    $query->execute([$name]);
    # Loop the results
    while($result = $query->fetch(\PDO::FETCH_ASSOC)) {
        # Store the tags
        $row[] = $result['color_name'];
    }
    # Return the tags or an empty array
    return (isset($row))? $row : [];
}

# Pull these out so you can use them in general
$name = "Your_Name"; // Assuming this is from the session
$email = "Your_Email"; // Assuming this is from the session
# Here is where you insert
if(isset($_POST['submit'])) {
    # This will insert your tags separately on new rows
    insertTags($_POST['selectname'], $email, $name, $con);
    # This will pull them back from the database (helpful if they already have some in there)
    $tags = getColorTags($email, $con);
}
# Here you check if there are tags already generated after submission,
# if not, then pull them.
if(!isset($tags))
    $tags = getColorTags($email, $con);
