[RESOLVED] PHP if else and while loop

[jamjam]

I want to control the output of php code with if else statement like this.

<?php if($row_director['director'] == "")
{echo "";} 
else {echo "
<table>
<th>
<h4>Directed by</h4>
</th>
<td>
<h5>
$row_director['director']
</h5>
<br />
</td>
</table>
<br />
";}?>

I also want to loop through the results contained in $row_director['director']

Having tried various ways to achieve this, I have now given up.

Can someone please help me.

Foreach() is your friend with arrays. I've left your HTML alone other than indenting it, but I think you should check that as well. In tables, last I checked, you need a <tr> container for a <td> to go into.

<?php if(!(is_array($row_director['director'] == ""))) {
   echo "";
}

else {
foreach ($row_director['director'] as $r) {
   echo "
   <table>
      <th>
         <h4>Directed by</h4>
      </th>
      <td>
         <h5>
            $r['director']
         </h5>
         <br />
      </td>
   </table>
   <br />
   ";
   }
}?>

HTH,

The code in the original post will generate a parse error unless you use curly braces ("complex variable notation") around the array variable in the string:

echo "This is a test of {$complex['key']} variable notation.";

The following will also work, though I don't like it because it's the only time it is correct to leave out the quotes around the array key, which I find very inconsistent.

echo "This is a test of $complex[key] variable notation.";

Also, is the array $row_director['director'] (and therefore multi-dimensional?) More likely it would be that $row_director is a one-dimensional array, so the code would be:

<?php if(!(is_array($row_director))) {
   echo "";
}

else {
foreach ($row_director as $r) {
   echo "
   <table>
      <th>
         <h4>Directed by</h4>
      </th>
      <td>
         <h5>
            $r['director']
         </h5>
         <br />
      </td>
   </table>
   <br />
   ";
   }
}?>

Good catch. I don't test everything.

Besides, it may not be true for everyone, but once I get the logic I can worry about syntax afterwards 😃

Hello dalecosp

Your solution looks good but I think it in the wrong order.

This is becuase there were no results show even through the database table has as at lease two rows meeting the condition.

Please double check this.

Thanks

General information: for debugging, an excellent resource is the "Debugging 101" thread found linked in my signature.

Now, a question for you, good sir. Is English your primary language? This:

... is an imperative statement. It might even be called a "command".

If indeed that is what you meant, and you are a native English speaker, be advised that I can gladly do exactly as you require for the very reasonable sum of $2.00/minute, billed in 30-minute units.

If English isn't your native language, I would offer the kind suggestion that you will get a better result if you type something more like this instead:

There are two rows in the database that should be shown. Could you please double check this and see why the results might be blank?

And it might be a good idea, then, to include the current code snippet:

<?php

// your modified script here
?>

and perhaps list any steps that you have taken yourself to determine why the current code is not working.

But these are just suggestions. 😉

I did not mean for my request to come-off as a command.

I did say please and thanks in the sentence, so I'm not sure why you took that way.

Anyway I have now worked out a solution for my original problem.

Thanks for all your help.
