0 Not recognised as php required field imput?

[Captain Salad]

Sorry to bug this forum with yet more of my woes but for some reason when I test my form, if I add a 0 (just a zero, nothing more) to a required field it doesnt pick it up and states that I missed a required field.

Any help on this one? Thanks you for any time and help,

God bless

The string '0' is considered empty, so will have to use a different method of validation if you want to allow zeros.

You can use:
[code]if ($_REQUEST['email'] == "")
{
     //not supplied
}[/code]

Or
[code]if ( strlen( trim( $_REQUEST['email'] ) ) > 0 )
{
    //supplied
}[/code]

Thanks for your input, I was afraid of that. Any help with the code I would need to add in order to allow 0? I am a total newb to PHP and coding of any sort so any further help will be greatly appreciated.

God bless

Hi, Thank you for trying to help me, so would this be correct?

$yearsataddress = if ($_REQUEST['yearsataddress'] == "")
{
//not supplied
}
$monthsataddress = $_REQUEST['monthsataddress'] ;

Try this, substitute the function empty in your script for checkLength
Example use: checkLength($title, 0, 50);
[code]// String length
// Usage:  checkLength(string to check length of, min length, max length)
function checkLength($string, $min, $max)
{
$length = strlen(trim($string));
    if ( ($length < $min) || ($length > $max) )
    {
    return FALSE;
    }
    else
    {
    return TRUE;
    }
}[/code]

Hi, thanks for you help, sadly I think I am way over my head as I cant get it to work still and not sure wher I should add the code (as I said I am total noob) , is there any chance you could be so kind as to amend the below code so that the $yearsataddress field proceses 0 if entered?

Sorry for all these pleas for help.

God bless

Put this anywhere on the page, I would put at the top though.
[code]// String length
// Usage:  checkLength(string to check length of, min length, max length)
function checkLength($string, $min, $max)
{
$length = strlen(trim($string));
    if ( ($length < $min) || ($length > $max) )
    {
    return FALSE;
    }
    else
    {
    return TRUE;
    }
}[/code]

Then change this code section:
[code]if (!isset($_REQUEST['email'])) {
header( "Location: http://www.brittalk.com/brittalk/Templates...actUs.htm" );
}
elseif (empty($email) || empty($transfer) || empty($title) || empty($firstname) || empty($lastname) || empty($dob) || empty($currentaddress)[/code]

To this (I would run the checkLength function on all fields)
[code]if (!isset($_REQUEST['email'])) {
header( "Location: http://www.brittalk.com/brittalk/Templates...actUs.htm" );
}
elseif (checkLength($email,1,40) || checkLength($transfer,1,50) )
// etc etc etc[/code]
If you just want it on the yearsataddress field, then change empty($yearsataddress) to checkLength($yearsataddress, 1, 5) or something. The 1 is the min number of digits, and the 5 is the max. Just change those numbers depending on how long or short the field can be.

Hi, I changed the code to what you suggested but I get an "error missed a field" message for no matter what I type in the fields, have I missed something, see edited code below.

sorry double post

I would change all the || into &&. And if you want to allow some fileds to be left blank, put the min value as 0. I have quickly done a test of whether it works and it works perfectly. This is the little bit of code I tested on.
[code]<?php
function checkLength($string, $min, $max)
{
$length = strlen(trim($string));
    if ( ($length < $min) || ($length > $max) )
    {
    return FALSE;
    }
    else
    {
    return TRUE;
    }
}

$name = trim(strip_tags($_POST['Name'])); // Name
$email = trim($_POST['Email']); // Email
    
if ( checkLength($email, 1, 50) && checkLength($name, 1, 50))
{
echo 'Passed validation';
}
else
{
echo 'Failed';
}

?>
    
    <form name="Contact" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
      <table class="padform">
    <tr><td><label for="Name">Name</label></td><td><input name="Name" id="Name" type="text" size="50" maxlength="50" value="<?php if ( isset($_POST['Name']) ) echo trim(strip_tags($_POST['Name'])); ?>" /></td></tr>
    <tr><td><label for="Email">Email</label></td><td><input name="Email" id="Email" type="text" size="50" maxlength="50" value="<?php if ( isset($_POST['Email']) ) echo trim($_POST['Email']); ?>" /></td></tr>
    <tr><td> </td><td align="center"><input name="Submit" type="submit" value="Contact" /></td></tr>
    </table>
    </form>[/code]
