[SOLVED] array problem

[shadiadiph]

I have the following array $keywords which is made up of $keyword1 to 4 if $keyword1 to 4 are empty I want $errorkeyword to be yes how can i do this ?

 

At the moment i have tried the following but it it obviously wrong ??

 

$keywords='';
$keywords= array($keyword1,$keyword2,$keyword3,$keyword4);  
if ($keywords==false) 
{
$action="addtext";
$errorkeyword="yes";
}

tried this also doesn't work

 

$keywords='';
$keywords= array($keyword1,$keyword2,$keyword3,$keyword4);  
if (!isset($keywords)) 
{
$action="addtext";
$errorkeyword="yes";
}

Do you want the error keyword to be yes if all of the array elements are empty? Or just if one of them is empty?

 

Also with the second way you have done it, isset will be true as you have put something into the array even if it is null. So there array would look some thing like.

 

array[0] = null

array[1] = null

array[2] = null

array[3] = null

 

etc..

 

you need to individualy test each array element

 

<?php
foreach ($keywords as $key=>$value) {

if($value == null) {
$errorkeyword="yes";
break;
}

}
?>

 

this will set errorketword to yes if one of the keys is null
