Give unique value for submit button - php

Question

In my table each and every row has a cell with a submit button.
Here is my code
<?php
# Init the MySQL Connection
mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("selfie") or die(mysql_error()) ;
# Prepare the SELECT Query
$selectSQL = 'SELECT * FROM `image_upload` INNER JOIN user_table
ON image_upload.user_id=user_table.user_id WHERE flag="0" ORDER BY timestamp DESC';
# Execute the SELECT Query
if( !( $selectRes = mysql_query( $selectSQL ) ) ){
echo 'Retrieval of data from Database Failed - #'.mysql_errno().': '.mysql_error();
}else{
?>
<table border="2">
<thead id="head">
<tr>
<th id="head">User name</th>
<th>Category</th>
<th>Description</th>
<th>Image</th>
<th>Location</th>
<th>Status</th>
</tr>
</thead>
<tbody>
<?php
if (isset($_GET['submit'])) {
$mobile = $_GET['dmobile'];
$query = mysql_query("update image_upload set
flag='$mobile' " );
}
if (isset($_GET['submit'])) {
header("Location: imageManagement.php");
}
if( mysql_num_rows( $selectRes )==0 ){
echo '<tr><td colspan="4">No Rows Returned</td></tr>';
}else{
while( $row = mysql_fetch_assoc( $selectRes ) ){
echo "<tr>
<td>{$row['user_name']}</td>
<td>{$row['category']}</td>
<td>{$row['description']}</td>
<td ><img src='uploads/".$row['image']."'width=300px height=200px></td>
<td>{$row['location']}</td>
<td><form class=\"form\" method=\"get\"><label></label><br/>
<input class=\"input\" type=\"text\" name=\"dmobile\" value=\" {$row['flag']}\" />
<br>
<input class=\"submit\" type=\"submit\" name=\"submit\" value=\"update\" />
</form></td>
</tr>\n";
}
}
?>
</tbody>
</table>
<?php
In here when do changes and click on submit button of one row each and every rows are updated. How can I give unique value for each and every submit button.

Answer 1

Comment to answer, since OP said it works.
OP: "It's work. Thank you very much.... :) – Lanka"
Add this to your form:
<input type=\"hidden\" name=\"the_id\" value=\"{$row['id']}\" />
then add:
$theid = $_POST['the_id'];
then,
$query = mysql_query("update image_upload set flag='$mobile'
WHERE id = '$theid' " );
You may need to play around with it a bit, in the hidden input that is.
This is based on having an "id" column of course.
N.B.:
You should validate the user input (even if it's a hidden field)
Use mysqli with prepared statements, or PDO with prepared statements, they're much safer.
As it stands, you are using a deprecated MySQL library, which leaves you open to SQL injection.

Answer 2

else{
$counter=0 ;
while( $row = mysql_fetch_assoc( $selectRes ) ){
$value="Update ".$counter ;
$counter++ ;
echo "<tr>
<td>{$row['user_name']}</td>
<td>{$row['category']}</td>
<td>{$row['description']}</td>
<td ><img src='uploads/".$row['image']."'width=300px height=200px></td>
<td>{$row['location']}</td>
<td><form class=\"form\" method=\"get\"><label></label><br/>
<input class=\"input\" type=\"text\" name=\"dmobile\" value=\" {$row['flag']}\" />
<br>
<input class=\"submit\" type=\"submit\" name=\"submit\" value=\"".$value."\" />
</form></td>
</tr>\n";
}
}
I do not think the question is clearly framed but by replacing the else part of your code with the above code you will get different values for submit button ie., update 0,update 1 and so on.. Hope this helps.
