<?php
/***********************************INSERT************************************************/
if($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST['submit']) == 'POST'){




            $valid_formats = array("jpg", "png", "gif", "bmp"); 
            $name = $_FILES["img"]["name"];
            $size = $_FILES["img"]["size"];
            //$temp = explode(".",$name);     
            //$ext = end($temp);            


           $target ="/uploads/$_FILES["img"]["tmp_name"];

            move_uploaded_file($_FILES["img"]["tmp_name"],$target_path);



}

?>


<form role="form" method="post" action="clients.php" enctype="multipart/form-data">

<table width="70%" height="30%" align="center">
<tr>
    <th>Choose Photo</th>
    <td><input type="file" name="img" id="file"></td>
</tr>
<tr>
<td><input type="submit" name="submit" value="POST" /></td>
</tr>
</table>
</form>
$target ="/uploads/$_FILES["img"]["tmp_name"]; // line 15

should be:

$target = "/uploads/" . $_FILES["img"]["tmp_name"];

and on line 17 $target_path should be $target I think.

No,Even though I get same 500 internal server error..

What's in your error log?

Just a note but your if statement has an error.

if($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST['submit']) == 'POST')

You're checking if a variable is set and then if the result is POST. You will need either:

isset($_POST['submit'])

Or

$_POST['submit'] == 'POST'

My recommendation would be the first.

The isset(); function can only return either TRUE or FALSE but you are checking to see if it has the value of POST. By just having isset($_POST['submit']) in the if statement, you are checking to see if it is set to TRUE. To check if it is false, you would change it to !isset($_POST['submit']).

The error log will be more precise as to the cause of the 500 error message. I don't think the error in the if statement would have caused a 500 error.

Try increase file execution time in php.ini

or

Check with max_upload_size in php.ini
