Delete query not working to delete stock - php

Question

i am implementing clothing shopping website in which admin manages stock for example add, update, delete stock. i am having problem with my delete query. stock is displayed in table and every row has its own delete button. when i click on delete button it always takes last row id and delete that and not that row which i want. Query is taking always last row id.
CODE:
<form action="" method="post" enctype="multipart/form-data" name="deleting" >
<table align="center" border="0" id="myTable" class="table table-striped table-bordered table-list">
<tr>
<th>Product Code</th>
<th>Brand</th>
<th>Price</th>
<th>Gender</th>
<th>Category</th>
<th>Material</th>
<th>Size</th>
<th>Description</th>
<th>Quantity</th>
<th>Delete Stock</th>
</tr>
<?php
$sql = "SELECT * FROM add_stock ORDER BY id DESC";
$rs_result = mysqli_query ($sql);
while ($result=mysqli_fetch_array($rs_result) )
{
?>
<tr>
<td><?php echo $result['id'];?></td>
<td><?php echo $result['brand_name'];?></td>
<td><?php echo $result['price'];?></td>
<td><?php echo $result['gender_name'];?></td>
<td><?php echo $result['category_name'];?></td>
<td><?php echo $result['material_name'];?></td>
<td><?php echo $result['size_name']; ?></td>
<td><?php echo $result['dress_description'];?></td>
<td><?php echo $result['dress_quantity'];?></td>
<td><input type="hidden" name="ID" value="<?php echo $result['id']; ?>"><input type="submit" name="delete" value="Delete" ></td>
</tr>
<?php
}
?>
</table>
</form>
<?php
if (isset($_POST['delete'])) {
$id=$_POST['ID']; //problem is here: it always takes last row id
$link=mysqli_connect("localhost","root","") or die("Cannot Connect to the database!");
mysqli_select_db("login",$link) or die ("Cannot select the database!");
$query="DELETE FROM add_stock WHERE id='".$id."'";
$result=mysqli_query($query,$link) or die(mysqli_error($link));
if($result)
{
echo '<script>confirm("Are you sure want to delete this record?")</script>';
echo '<script>alert("Record ".$id." removed successfully!")</script>';
}
else
{
die ("An unexpected error occured while <b>deleting</b> the record, Please try again!");
}
}
?>

Answer 1

I would rather suggest not to use <form> just for deleting purpose. You can use <a> tag to redirect it to other page for deleting purpose.
Here is my code.
index.php
<table align="center" border="0" id="myTable" class="table table-striped table-bordered table-list">
<tr>
<th>Product Code</th>
<th>Brand</th>
<th>Price</th>
<th>Gender</th>
<th>Category</th>
<th>Material</th>
<th>Size</th>
<th>Description</th>
<th>Quantity</th>
<th>Delete Stock</th>
</tr>
<?php
$sql = "SELECT * FROM add_stock ORDER BY id DESC";
$rs_result = mysqli_query($sql);
while ($result = mysqli_fetch_array($rs_result)) {?>
<tr>
<td><?php echo $result['id']; ?></td>
<td><?php echo $result['brand_name']; ?></td>
<td><?php echo $result['price']; ?></td>
<td><?php echo $result['gender_name']; ?></td>
<td><?php echo $result['category_name']; ?></td>
<td><?php echo $result['material_name']; ?></td>
<td><?php echo $result['size_name']; ?></td>
<td><?php echo $result['dress_description']; ?></td>
<td><?php echo $result['dress_quantity']; ?></td>
<td>
<a href="deleteStock.php?id=<?php echo $result['id'];?>">
<input type="button" value="Delete" >
</a>
</td>
</tr>
<?php }?>
</table>
<?php
if(isset($_GET['delete'])){
if($_GET['delete'] == "success"){
echo '<script>alert("Record removed successfully!")</script>';
}
if($_GET['delete'] == "fail"){
echo '<script>alert("An unexpected error occured while <b>deleting</b> the record, Please try again!")</script>';
}
}
?>
<script>
$(document).on('click', "#myTable a", function(e) {
if(confirm("Are you sure want to delete this record?")) {
return true;
} else {
return false;
}
});
</script>
deleteStock.php
<?php
if (isset($_GET['id'])) {
$id = $_GET['id'];
$link = mysqli_connect("localhost", "root", "") or die("Cannot Connect to the database!");
mysqli_select_db("login", $link) or die("Cannot select the database!");
$query = "DELETE FROM add_stock WHERE id = $id";
$result = mysqli_query($query, $link) or die(mysqli_error($link));
if($result){
header("location:index.php?delete=success");
} else {
header("location:index.php?delete=fail");
}
}?>
[Important: And, still you have not created separate file for DB Connection, which I have already mentioned in my answer of your question modal popup keep populating only first item data on all item buttons 1 Week before. It implies, you don't learn from your mistake or you don't need any suggestions.]

Answer 2

Your script taking last row in post always because you have single form for all your data and your last value will be overwrite all previous data. Intead of it remove form from out side of table add add it to td where you have specify hidden field and delete button. Like below:
<table align="center" border="0" id="myTable" class="table table-striped table-bordered table-list">
<tr>
<th>Product Code</th>
<th>Brand</th>
<th>Price</th>
<th>Gender</th>
<th>Category</th>
<th>Material</th>
<th>Size</th>
<th>Description</th>
<th>Quantity</th>
<th>Delete Stock</th>
</tr>
<?php
$sql = "SELECT * FROM add_stock ORDER BY id DESC";
$rs_result = mysqli_query ($sql);
while ($result=mysqli_fetch_array($rs_result) )
{
?>
<tr>
<td><?php echo $result['id'];?></td>
<td><?php echo $result['brand_name'];?></td>
<td><?php echo $result['price'];?></td>
<td><?php echo $result['gender_name'];?></td>
<td><?php echo $result['category_name'];?></td>
<td><?php echo $result['material_name'];?></td>
<td><?php echo $result['size_name']; ?></td>
<td><?php echo $result['dress_description'];?></td>
<td><?php echo $result['dress_quantity'];?></td>
<td><form action="" method="post" name="deleting" ><input type="hidden" name="ID" value="<?php echo $result['id']; ?>"><input type="submit" name="delete" value="Delete" ></form></td>
</tr>
<?php
}
?>
</table>
Also Remove enctype="multipart/form-data" from form its needed only if you have to upload file
