我使用 HTML 表单将数据插入到数据库表中。我想要做的是显示我使用 HTML 表单插入的数据。我使用关联数组从数据库中获取正确的数据。但我只能显示表格中的一行。我不知道为什么我的代码不显示我插入的其他数据。
这是我的代码:
<?php
$part_insert_message = "";
enter code here
session_start();
$inserted_parts = array();
$part_inserted_id;
if(isset($_POST['submit'])) {
require "/Basics/Mysql_Connect/mysql_connect.php";
$sql="INSERT INTO Parts (SKU, Part, Description, Quantity, Price)
VALUES
('$_POST[sku]', '$_POST[categories]', '$_POST[description]', '$_POST[quantity]', '$_POST[price]')";
$result = mysqli_query($con, $sql);
if (!$result)
{
die('Error: ' . mysqli_error($con));
}
$part_inserted_id = mysqli_insert_id($con);
$inserted_parts[$part_inserted_id] = $part_inserted_id;
// store session data
$_SESSION['views']= $inserted_parts;
$part_insert_message = "ID: " . $part_inserted_id . " Part: " . $_POST['sku'];
mysqli_close($con);
}
?>
<?php
// This block grabs the whole list for viewing
$product_list = "";
if(isset($_SESSION['views'])){
$inserted_parts = $_SESSION['views'];
}
if(!empty( $inserted_parts )) {
require "/Basics/Mysql_Connect/mysql_connect.php";
foreach($inserted_parts as $key => $value){
$sql = "SELECT * FROM Parts WHERE PartID='$key'";
$result = mysqli_query($con, $sql);
if (!$result)
{
die('Error: ' . mysqli_error($con));
}
$productCount = mysqli_num_rows($result); // count the output amount
if ($productCount > 0) {
while($row = mysqli_fetch_array($result)){
$partID = $row["PartID"];
$sku = $row["SKU"];
$part = $row["Part"];
$description = $row["Description"];
$quantity = $row["Quantity"];
$price = $row["Price"];
$product_list .= "Product ID: $partID - <strong>$sku</strong> - $$price - <em>Part $part</em> <a href='Add_Delete_Part.php?deleteid=$partID'>delete</a><br />";
}
}else {
$product_list = "You have no products listed in your store yet";
}
}
mysqli_close($con);
}
?>
<?php
require "/Basics/Mysql_Connect/mysql_connect.php";
// Delete Item Question to Admin, and Delete Product if they choose
if (isset($_GET['deleteid'])) {
echo 'Do you really want to delete product with ID of ' . $_GET['deleteid'] . '? <a href="Add_Delete_Part.php?yesdelete=' . $_GET['deleteid'] . '">Yes</a> | <a href="Add_Delete_Part.php">No</a>';
exit();
}
if (isset($_GET['yesdelete'])) {
// remove item from system and delete its picture
// delete from database
$id_to_delete = $_GET['yesdelete'];
$sql = "DELETE FROM Parts WHERE PartID='$id_to_delete'";
$result = mysqli_query($con, $sql);
if (!$result)
{
die('Error: ' . mysqli_error($con));
}
// unlink the image from server
// // Remove The Pic -------------------------------------------
// $pictodelete = ("../inventory_images/$id_to_delete.jpg");
// if (file_exists($pictodelete)) {
// unlink($pictodelete);
// }
header("location: Add_Delete_Part.php");
exit();
}
mysqli_close($con);
?>
