Only issue LI once

[unemployment]

How can I make it say... if none of the values in the array = $is_assoicate then do stuff...

 

Right now it adds an li every time a value is not in the array.  I only want it to add in 1 LI

 

<?php

			foreach($users_associates as $is_associate)
			{
				if ($is_associate['user_id'] != $user_info['uid'])
				{
					?>
					<li class="bass">
						<a href="" title="Become Associates" id="becomeassoc" class="mll">
							<span class="f_right">Become Associates</span><img src="../assets/img/becomeassoc.jpg" class="mrs vmiddle" alt="Become Associates" />
						</a>
					</li>
					<?php
				}
			}

		?>

foreach($users_associates as $is_associate)
			{
				if (($is_associate['user_id'] != $user_info['uid'])&&$count<=0)
				{
$count++;						
?>
					<li class="bass">
						<a href="" title="Become Associates" id="becomeassoc" class="mll">
							<span class="f_right">Become Associates</span><img src="../assets/img/becomeassoc.jpg" class="mrs vmiddle" alt="Become Associates" />
						</a>
					</li>
					<?php
				}
			}

that didn't work for me.  $count is undefined.

[dawsba]

at the top of the script just add

$count=0;

[unemployment]

still fails... It does seem to check all of the keys of the $is_associate array.

This list the li several times, because it runs through all of the array values.  Instead of issuing an li every time that ($is_associate['user_id'] != $user_info['uid'])  I only want it to issue one li if none of the keys in the $is_associate['user_id'] array = $user_info['uid']

 

<?php

foreach($users_associates as $is_associate)
{	
if ($is_associate['user_id'] != $user_info['uid'])
{
	?>
	<li class="bass">
		<a href="" title="Become Associates" id="becomeassoc" class="mll">
			<span class="f_right">Become Associates</span><img src="../assets/img/becomeassoc.jpg" class="mrs vmiddle" alt="Become Associates" />
		</a>
	</li>
	<?php
}
}

?>

Try using the array_key_exists function.

foreach($users_associates as $is_associate)
{	
if (!array_key_exists($user_info['uid'], $is_associate['user_id']))
{
	?>
	<li class="bass">
		<a href="" title="Become Associates" id="becomeassoc" class="mll">
			<span class="f_right">Become Associates</span><img src="../assets/img/becomeassoc.jpg" class="mrs vmiddle" alt="Become Associates" />
		</a>
	</li>
	<?php
}
}

That didn't seem to work.  I got this error.

 

Warning: array_key_exists() expects parameter 2 to be array,

 

$user_info['uid']  is not an array.  The only array here is the $users_associates array

[dcro2]

That would have been nice to know.. you said it was.

if (!array_key_exists($user_info['uid'], $users_associates))
{
?>
<li class="bass">
	<a href="" title="Become Associates" id="becomeassoc" class="mll">
		<span class="f_right">Become Associates</span><img src="../assets/img/becomeassoc.jpg" class="mrs vmiddle" alt="Become Associates" />
	</a>
</li>
<?php
}

Remember, this is checking if there's an array key that matches ($array['key'] = 'value'), not an array value. If you want to check for a value use in_array

Thanks... I did need in_array, but I still can't get it to work..

 

My output for $user_info['id']; = 1

 

echo '<pre>';

print_r($users_associates);

 

Array

(

    [0] => Array

        (

            [user_id] => 3

        )

 

    [1] => Array

        (

            [user_id] => 14

        )

 

    [2] => Array

        (

            [user_id] => 1

        )

 

    [3] => Array

        (

            [user_id] => 4

        )

 

    [4] => Array

        (

            [user_id] => 6

        )

 

    [5] => Array

        (

            [user_id] => 19

        )

 

)

 

The value is in the array, but yet, the li is still being added.

 

<?php
			echo $user_info['uid'];
			echo '<pre>';
			print_r($users_associates);
			if (!in_array($user_info['uid'], $users_associates))
			{
				?>
				<li class="bass">
					<a href="" title="Become Associates" id="becomeassoc" class="mll">
						<span class="f_right">Become Associates</span><img src="../assets/img/becomeassoc.jpg" class="mrs vmiddle" alt="Become Associates" />
					</a>
				</li>
				<?php
			}

		?>

Right, because you have a multidimensional array there. in_array will only check one dimension. You were on the right track when you posted this, but since you just need to know if it's found try this:

				$found = false;
			foreach($users_associates as $associate)
			{
				if($associate['user_id'] == $user_info['uid']) {
					$found = true;
					break;
				}
			}

			if(!$found) {
				?>
				<li class="bass">
					<a href="" title="Become Associates" id="becomeassoc" class="mll">
						<span class="f_right">Become Associates</span><img src="../assets/img/becomeassoc.jpg" class="mrs vmiddle" alt="Become Associates" />
					</a>
				</li>
				<?php
			}

I suppose you could also do this if each $users_associates contains just an array with a 'user_id' key.

That worked.  Thank you!
