无法将两个数组值插入数据库

Question

这是我用于为数据库中的每个条目上传多张图片的代码； ID、图像、名称、日期。通过使用此代码，图像名称可以正确插入，但名称字段有问题。我想使用 $product_name= $_POST['pro_name']; 插入名称，但它只会在名称字段中插入 'array'。

<?php
include('../config.php');
if (isset($_POST['submit'])) {
    $product_name = $_POST['pro_name'];

    $j = 0;     // Variable for indexing uploaded image.
    $target_path = "uploads/";     // Declaring Path for uploaded images.
    for ($i = 0; $i < count($_FILES['file']['name']) && $product_name < count($product_name); $i++) {
        // Loop to get individual element from the array
        $validextensions = array("jpeg", "jpg", "png");      // Extensions which are allowed.
        $ext = explode('.', basename($_FILES['file']['name'][$i]));   // Explode file name from dot(.)
        $file_extension = end($ext); // Store extensions in the variable.
        $target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext) - 1];     // Set the target path with a new name of image.
        $j = $j + 1;      // Increment the number of uploaded images according to the files in array.
        if (($_FILES["file"]["size"][$i] < 100000000)     // Approx. 100kb files can be uploaded.
                && in_array($file_extension, $validextensions)) {

            if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {

                $finel_name = explode('/', $target_path);
                $image_name_final = $finel_name[1];
                $jajsj = "insert into spec_product set image='$image_name_final', name='$product_name'";
                $janson = mysql_query($jajsj) or die(mysql_error());
                // If file moved to uploads folder.
                echo $j . ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';
            } else {     //  If File Was Not Moved.
                echo $j . ').<span id="error">please try again!.</span><br/><br/>';
            }
        } else {     //   If File Size And File Type Was Incorrect.
            echo $j . ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
        }
    }
}
?>

Answer 1

值作为数组插入，因为变量 $product_name 不是字符串而是数组。每当在需要字符串的地方使用数组时，例如：字符串的连接或在您的情况下查询语句：insert into spec_product set image='$image_name_final', name='$product_name'"; PHP 会自动将数组转换为其默认字符串值 "Array".

确保 $product_name 不是一个数组，而是一个字符串，其中包含您要插入到 table 中的产品名称。

替换成你的代码

for ($i = 0; $i < count($_FILES['file']['name']); $i++)
    {

并在你的查询执行之前添加这个

$product_name_final= $product_name[$i];
