Question

I’m trying to retrieve information from database with submit buttons , which have the same name . I’m giving value which is id of the row , so I could make a different actions, but I can not make up my mind how to do that .

When trying like this for example

<form name="form" action="index.php" method="post">
<input type="image" name="x" value="1">

<input type="image" name="x" value="2">
</form>

and php =>

<?php
if (isset($_POST['x'])){
    echo $_POST['x'];
}
?>

in chrome it works fine , but in other browsers it doesn’t , any ideas ? thanks

UPDATE

if ($r = $con->query("SELECT * FROM table")){
    if ($row = $r->fetch_assoc()){
        echo "<input type='image' name='submit' value='" . $row['id'] . "'>";
        // and other data which I need to
    }
    $r->free();
}

I meant like this

HTML

<form id="form1" action="index.php" method="post">
   <input type="button" name="x" value="1">    
   <input type="button" name="x" value="2">
   <input type="text" name="action" id="action">
</form>​

​
JavaScript

var nodes = document.getElementById('form1').childNodes;
for(var i=0; i<nodes.length; i++) {    
    nodes[i].onclick = function(){        
        if(this.name == 'x'){
          document.getElementById('action').value = this.value;
        }
    };
}

PHP

if(isset($_POST['action'])){

   if($_POST['action'] == "1"){
      ...
   }

   if($_POST['action'] == "2"){
      ...
   }

}

Just change type="text" to type="hidden" when ready to deploy.

Alternatively with no JavaScript:

<form action="index.php" method="post">
   <button type="submit" name="action" value="delete">Delete</button>
</form>​
<form action="index.php" method="post">
   <button type="submit" name="action" value="copy">Copy</button>
</form>​
<form action="index.php" method="post">
   <button type="submit" name="action" value="edit">Edit</button>
</form>​
