[SOLVED] Echo within echo?

[geektasic]

Hey all,

 

I'm using a css rollover technique which shifts the background image of my navigation items. I'm also using php if statement to implement my sub menus. Here's the code my sub menu uses. The id is controlled via php switch.

 

<li><a id="<? echo $rollover_id; ?>" class="navigation_class" href="index.php?linkn"><span class="navigation_span">Link</span></a></li>

<!-- Sub menu-->
<?

if ( $sub_menu == "true" ) {
echo "

<li><a id=\"button_rollover\" class=\"navigation_class\" href=\"index.php?link1\"><span class=\"navigation_span\">Link 1</span></a></li>

<li><a id=\"button_rollover\" class=\"navigation_class\" href=\"index.php?link2\"><span class=\"navigation_span\">Link 2</span></a></li>

<li><a id=\"button_rollover\" class=\"navigation_class\" href=\"index.php?link3\"><span class=\"navigation_span\">Link 3</span></a></li>

";
}
?>

 

Within the submenu, is it possible to insert an echo so I can define my rollover for the submenu id? I.e. can I replace "button_rollover" with $rollover_id? I'd like to do this so I can make the button active when you're on that page.

 

I hope this makes sense. I'm quite new to PHP, so thank you for your patience.

change it to this...

<li><a id="<?php echo $rollover_id; ?>" class="navigation_class" href="index.php?linkn"><span class="navigation_span">Link</span></a></li>

<!-- Sub menu-->
<?php

if ( $sub_menu == "true" ) {
echo "<li><a id=\"".$rollover_id."\" class=\"navigation_class\" href=\"index.php?link1\"><span class=\"navigation_span\">Link 1</span></a></li>";

echo "<li><a id=\"".$rollover_id."\" class=\"navigation_class\" href=\"index.php?link2\"><span class=\"navigation_span\">Link 2</span></a></li>";

echo "<li><a id=\"".$rollover_id."\" class=\"navigation_class\" href=\"index.php?link3\"><span class=\"navigation_span\">Link 3</span></a></li>";
}
?>

Strange, it doesn't seem to work. When I use that technique, it prints the ID as blank in the html.

[MasterACE14]

with the link at the very top does it display it in the link?

[geektasic]

In the html, using your technique, it reads in the HTML:

 

<li><a id="" class="navigation_class" href="index.php?link1"><span class="navigation_span">Link 1</span></a></li>

 

 

[MasterACE14]

then $rollover_id doesn't appear to be set.

 

add to your script some where...

<?php
if(!isset($rollover_id)) {
  echo "rollover_id is not set!";
}
?>

[geektasic]

Good point! I hadn't set $rollover_id! Thank you for your help. One last question... with what you mentioned about the !isset, where exactly would I place that in my current sub menu code? It's a useful little bit of code which I'd like to play with.

[MasterACE14]

you can do something like...

<?php if(isset($rollover_id)) { ?>
<li><a id="<?php echo $rollover_id; ?>" class="navigation_class" href="index.php?linkn"><span class="navigation_span">Link</span></a></li>

<!-- Sub menu-->
<?php

if ( $sub_menu == "true" ) {
echo "<li><a id=\"".$rollover_id."\" class=\"navigation_class\" href=\"index.php?link1\"><span class=\"navigation_span\">Link 1</span></a></li>";

echo "<li><a id=\"".$rollover_id."\" class=\"navigation_class\" href=\"index.php?link2\"><span class=\"navigation_span\">Link 2</span></a></li>";

echo "<li><a id=\"".$rollover_id."\" class=\"navigation_class\" href=\"index.php?link3\"><span class=\"navigation_span\">Link 3</span></a></li>";
}

} else {
  echo "No Available Links!";
}
?>
