Show value of multiple invalid input in textarea

[IreneLing]

Hi all .

In my scripts , there is a textbox that allow user to enter multiple phone number separate with "," , if all valid it will echo "ok!" else will echo "error" .

 

How if I want to know which value is in wrong format? such as I entered "0112255666,445221122200" , then it will echo " 445221122200 is not a valid phone number" .

 

And how to echo the total phone number inserted to the textarea ?

 

Thanks for every reply .

 

<?php
if (isset($_POST["Submit"])) {

$arrLines = split(",",$_POST['cellphonenumber']);

foreach($arrLines as $cells){

if(!preg_match('/^[0]{1}[1]{1}[0-9]{1}[0-9]{7}?$/', $cells)){
echo "error";
}
else{
echo "ok!";
}

}
}
?>

<form action="<?php echo $_SERVER['PHP_SELF'] ?>" name="myform" method="post">
<textarea name="cellphonenumber" rows="20" cols="100"></textarea>
<input type="submit" name="Submit" />
</form>

In your "error" section where you echo "error" also echo the $cells value?  As for counting the total number of successful add an incrementor that adds 1 every time it was successful and then outside of your foreach loop echo that value.

 

Does this make sense?

Thanks for your reply juddster , ok I understand the total number of successful add now , really thank you .

 

In this scripts , it will just simply echo "error" or "ok" at the bottom of textarea , just a very simple code so I not yet arrange where to display the error message properly .

I'm not sure what you mean for the error section.  Did you want it to have a list like:

error 123456

error 1234567

 

etc?

 

Or something else?

Thanks for your reply again .

 

Let's say , I enter "0164455888,0147788555,2365412258,221145589" (my cell number must start with 0 ) , so now there are 2 numbers are invalid .

then after I click Submit button it will echo  :

 

" 2365412258 , 221145589 is not valid number"

 

or

 

" 2365412258  is not valid number"

"  221145589 is not valid number".

 

Is it something related to trim?I'm not sure how to do this part...

 

Thanks again .

Either you can build an array of all of the errors and output it like you have it the first way, or just echo it as you go to get the output like you have the second way.

<?php
if (isset($_POST["Submit"])) 
{

    $arrLines = split(",",$_POST['cellphonenumber']);

    $errors = array ();

    foreach($arrLines as $cells)
    {

        if(!preg_match('/^[0]{1}[1]{1}[0-9]{1}[0-9]{7}?$/', $cells))
        {
            $errors [] = $cells;
        }
    }
}

if ( count ( $errors ) == 0 )
{
    echo 'All Successful';
}
else
{
    foreach ( $errors as $error )
    {
        echo $error;
    }

    echo ' is not a valid number.';
}
?>

<form action="" name="myform" method="post">
<textarea name="cellphonenumber" rows="20" cols="100"></textarea>
<input type="submit" name="Submit" />
</form>

Worth pointing out that split() has was deprecated in favour of preg_split() as of PHP 5.3.0. So might be worth changing this now rather than later and avoid headaches.
