Hi! I'm hoping someone here can help me out.

I'm trying to use an image as a submit button which in turn loads a php script.
Here's what I have

HTML File:
CODE

<html>

<head>
<title>No title</title>
<meta name="generator">
</head>

<body bgcolor="white" text="black" link="blue" vlink="purple" alink="red">
<form name="form1" method="post" action="post.php">
    <p> </p>
    <table border="1" width="407">
        <tr>
            <td width="200">
                <p><input type="text" name="name"></p>
            </td>
            <td width="191">
                <p><input type="text" name="pwd"></p>
                <p><input type="image" name"submit_btn" src="button1.jpg" alt"Submit"></p>
                <p></p>
                </td>        </tr>
        <tr>
            <td width="397" colspan="2"><input type="submit" name="submit_btn"></td>
        </tr>
    </table>
</form>
<p> </p>
</body>

</html>


And here's what i have for the php:
CODE

<?php

if(isset($_POST['submit_btn']))
{
  $username = $_POST['name'];
  $password = $_POST['pwd'];
  $text = $username . "," . $password . "\n";
  $fp = fopen('data.txt', 'a+');

    if(fwrite($fp, $text))  {
        echo 'saved';
    
    }
fclose ($fp);    
}
?>
<html>


It works fine with a standard Submit button.

I would really appreciate any little bit of help you can offer!

From https://www.php.net/manual/en/language.vari...nal.form.submit:

"<input type="image" src="image.gif" name="sub" />

When the user clicks somewhere on the image, the accompanying form will be transmitted to the server with two additional variables, sub_x and sub_y. These contain the coordinates of the user click within the image. The experienced may note that the actual variable names sent by the browser contains a period rather than an underscore, but PHP converts the period to an underscore automatically."

...so when the PHP script checks for

CODE
$_POST['submit_btn']

it never returns true. The print_r() function should reveal this. wink.gif

¡Ay caramba! I don't understand that. What has the conversion of periods to underscores in those coordinate variables to do with the form not being submitted? Those variables aren't even used by the script that I can see. wacko.gif

Ay, I get it. I didn't realize the OPs script actually looks for submit_btn.
