[RESOLVED] Post data anomaly

[HeidiR]

Hello All,

I am experiencing some odd behavior with a form field with a default value.

The form field code is:
<input name=txt_counter type=text maxlength=5 size=5 value='0'>

The $_POST array looks like this:
Array ([submit_button] => 1 [txt_counter] => 0 )

The anomalous code and results are as follows:

if (strlen($POST['txt_counter'] == 0)) $error=TRUE;
echo ('error: ' . $error); //displays 1
echo ('len : ' . strlen($POST['txt_counter'])); //displays 1

if (!is_numeric($_POST['txt_counter'])) $error=TRUE;
echo ('error: ' . $error); //displays 1

I must need a new pair of eyes! What am I missing???

My first guess is you have a wayward paren around your strlen(). The closing paren needs to be after ...'tx_counter']) not after ... ==0))

if (strlen($_POST['txt_counter'] == 0)) $error=TRUE;

should be

if (strlen($_POST['txt_counter']) == 0) $error=TRUE;

That was it! I knew it was something stupid! Thanks for your help!
