Post Form and Update Multiple Rows with MySQL
In this scenario, we aim to create a form that enables backend users to modify the titles and tags of multiple photos associated with a specific gallery. After form submission, these changes should be applied simultaneously to all selected rows in the database.
Form Structure
The provided code grabs photos from the database using the gallery ID and displays them as a form with input fields for title and tags. These fields are linked to hidden inputs containing the photo ID.
// Fetch photos from the database $result = $db->prepare("SELECT * FROM photos WHERE gallery_id = :gallery_id "); $result->bindParam(':gallery_id', $id); $result->execute(); // Generate input fields for each photo echo '<form action="" method="POST">'; echo "<ul id='photos'>"; for ($i = 0; $row = $result->fetch(); $i++) { // Get photo details $id = $row['id']; $title = $row['title']; $tags = $row['tags']; $src = $row['src']; // Create input fields echo "<li><a class='lightbox' href='images/$src'><img src='images/$src' id='$id' alt='$title' /></a><br />"; echo "<input type='text' name='photo_title[]' value='$title' /><br />"; // ***** Adjusted the array submission ***** echo "<input type='text' name='photo_tags[]' value='$tags' /><br />"; // ***** Adjusted the array submission ***** echo "<input type='hidden' name='photo_id[]' value='$id' />"; // ***** Adjusted the array submission ***** echo "</li>"; } echo "</ul>"; echo '<div style="clear:both"></div>';
