Passing a text field as a variable

[Navajo]

Hi guys,

 

<input name="prodass" type="text" id="prodass" value="<?php echo $row2['vchar_assessment_limit'] ?>" size="32" />

 

I have this text box on my page, I also have this Save button.

 

      <FORM METHOD="LINK" ACTION="saveEdit.php?"><INPUT TYPE="submit" VALUE="Save"></FORM>

 

How can I get it so that when saveEdit.php is called the new value of the text box is passed?

Well, you have several problems, the biggest of which is your confusion about how values are passed to the script by a form.

 

First, 'link' is not a valid form method.  You have two choices - post and get.  Post sends values to the server behind the scenes.  Get sends values as a query string appended to the end of a URL.  In most cases, you want to use post.

 

Sending form values to PHP is ridiculously easy.  In your form, simply choose a method (post or get), and give each input a name.  Then, in the PHP script (given by the action attribute of the form), you can access your inputs by simply writing:

 

<?php
   $formInput = $_POST['inputName'];

   //Or

   $formInput = $_GET['inputName'];
?>

 

Where inputName is the name you gave your form input in the HTML, and $_POST/$_GET is the form method you used.

hi, thanks for your reply

 

I now have,

 

<input name="prodass" type="text" id="prodass" value="<?php echo $row2['vchar_assessment_limit'] ?>" size="32" />
</center>
    
<?php $formInput = $_GET['prodass']; ?>

    
    
    
    
    <FORM METHOD="LINK" ACTION="viewproductcodes.php"><INPUT TYPE="submit" VALUE="Cancel"></FORM>

    <?php  

echo "<FORM METHOD=\"GET\" ACTION=\"saveEdit.php?win=$formInput\"><INPUT TYPE=\"submit\" VALUE=\"Save\"></FORM>"

?>

 

I'm getting Notice: Undefined index: prodass

 

I'm stuck :s

?>
    
    
    
    
    </FORM>

Notice: Undefined index: prodass in E:\Apache2\htdocs\2007\productupdates\editDatabase.php on line 83

 

Notice: Undefined variable: prodass in E:\Apache2\htdocs\2007\productupdates\editDatabase.php on line 91

 

 

help

$prodass2 = (isset($_POST['prodass']))?$_POST['prodass']:null;

 

Should remove those notices. They are showing up because the form probably has not been posted. This will prevent that error if that is the case.
