problem with if statments

[amarafzal]

Hi

i got a problem with following if statment. Only 2 parts of it work. Can you tell me where im going wrong? im a newbie

if ($POST['keyword'])
{
echo "this is keyword only selected";
}
elseif ($POST['keyword'] && $POST['job_sector'])
{
echo "this is keyword and job_sector";
}
elseif ($POST['keyword'] && $POST['region'])
{
echo "this is keyword and region";
}
elseif ($POST['job_sector'] && $POST['region'])
{
echo "this is job_sector and region";
}
elseif ($POST['job_sector'])
{
echo "this is job_sector";
}
elseif ($POST['region'])
{
echo "this is region";
}
elseif ($POST['keyword'] && $POST['job_sector'] && $POST['region'])
{
echo "this is keyword, job_sector, and region";
}

try changing them to isset()

if(isset($_POST['keyword'])

if that fails

if(isset($POST['keyword'] && $POST['keyword']!="")

Good luck

thanks for that but none of that worked, with second one im getting parse error

any more ideas im getting desperate:mad: :mad:

[amarafzal]

ive got some of it working:

if(isset($POST['keyword']) && $POST['keyword']!="")
{
echo "this is keyword only selected";
}
else if(isset($POST['keyword']) && $POST['keyword']!="" && isset($POST['job_sector']) && $POST['job_sector']!="")
{
echo "this is keyword and job_sector";
}else{
echo"pis off";
}

the first if statment works, the second else if statment doesnt work and the else works aswell.

i worked out the problem, if the keyword is filled in the script will stop at the first if, it wont go on. How can i avoid this problem?

HELPP!!!!!

This

if(isset($_POST['keyword']) && $_POST['keyword']!="")

Can be written more succinctly as

if(!empty($_POST['keyword']))

Now, if your echo'd statements are anything to go by, your logic is a bit confused. The first if statement is true no matter what job_sector is or whether it's set or not - obvious, really, since it doesn't even mention job_sector any more than it mentions rice_pudding. So whenever $_POST['keyword'] is not empty, the first branch ('this is keyword only selected') will be executed. The second branch never will, because the program will never get to that point.

Say $POST['keyword'] is empty. The program will skip over the first branch, skip over the second branch, and run the third branch. $POST['job_sector'] has nothing to do with this.

On the other hand, say $_POST['keyword'] is not empty. The program will run the first branch. The second branch is never reached.

Obviously, we want to look at $_POST['job_sector'] at some point before we decide which branch to take. A wee bit of rearranging will fix things.

if(!empty($_POST['keyword']) && !empty($_POST['job_sector']))
{
	echo "this is keyword and job_sector";
}
elseif(!empty($_POST['keyword']))
{
	echo "this is keyword only selected";
}
else{
	echo"pis off";
} 

And that could be simplified even further.

if(!empty($_POST['keyword'])
{	if(!empty($_POST['job_sector']))
	{
		echo "this is keyword and job_sector";
	}
	else
	{
		echo "this is keyword only selected";
	}
}
else
{	echo"pis off";
}

And isn't that easier to read when [PHP] tags are used?

im trying to add more elseif to if statment: the new bit in red doesnt work, what am i doing wrong?

if(!empty($POST['keyword']) && !empty($POST['job_sector']))
{
echo "this is keyword and job_sector";
}
elseif(!empty($POST['keyword']))
{
echo "this is keyword only selected";
}
elseif(!empty($POST['keyword']) && !empty($_POST['region']))
{
echo "this is keyword and region selected";
}
else{
echo"pis off";
}

[amarafzal]

the full complete thing im trying to do, but it doesnt work in that it brings the wrong echo statments, is it becasue i arranged in it the wrong way?

if(!empty($POST['keyword']) && !empty($POST['job_sector']) && !empty($POST['region']))
{
echo "this is keyword, job_sector and region";
}
elseif(!empty($POST['keyword']) && !empty($POST['job_sector']))
{
echo "this is keyword and job_sector";
}
elseif(!empty($POST['keyword']) && !empty($POST['region']))
{
echo "this is keyword and region";
}
elseif(!empty($POST['job_sector']) && !empty($POST['region']))
{
echo "this is job_sector and region";
}
elseif(!empty($POST['job_sector']))
{
echo "this is job_sector only selected";
}
elseif(!empty($POST['region']))
{
echo "this is region only selected";
}
elseif(!empty($POST['keyword']))
{
echo "this is keyword only selected";
}
else{
echo"pis off";
}

JUST TO LET YOU KNOW IVE GOT IT WORING

the reason they aren't working as you thought is cuz you aren't doing them as i told you to do them, you need to get more specific, for example, say you have keyword, title, and summary, you do this, keep in mind this is just an example and you will have to change it to meet your needs, and also, whatever number of fields you have to check on, for example if you have 4, simple do this: 4321 to figure out how many combinations of if's you can have, for my example of 3, 32*1, you have 6 if/else statements, try it out

<?
if ($_POST['keyword'] && !$_POST['title'] && !$_POST['summary'])
{
echo "keyword only";
}
else if (!$_POST['keyword'] && $_POST['title'] && !$_POST['summary'])
{
echo "title only";
}
else if (!$_POST['keyword'] && !$_POST['title'] && $_POST['summary'])
{
echo "summary only";
}
else if ($_POST['keyword'] && !$_POST['title'] && $_POST['summary'])
{
echo "keyword and summary";
}
else if ($_POST['keyword'] && $_POST['title'] && !$_POST['summary'])
{
echo "keyword and title";
}
else if (!$_POST['keyword'] && $_POST['title'] && $_POST['summary'])
{
echo "title and summary";
}
?>

Weedpacket ...

if(isset($_POST['keyword']) && $_POST['keyword']!="")

... and ...

if(!empty($_POST['keyword']))

are not the same. Pretty close, but the first one will allow a user to use 0 in a form also ("0").
