[SOLVED] help with css inside php

[CyberShot]

I am following a tutorial and I can not figure out why my css class isn't working. I have class set to make a link bold when you select it. but it doesn't work for me.

 

$subject_set = get_all_subjects();
				while($subject = mysql_fetch_array($subject_set))
				{
				echo "<li";
				if($subject["id"] == $sel_subj) {
				echo "class=\"selected\"";
				}
				echo "><a href=\"content.php?subj=" . urlencode($subject["id"]) . "\"> {$subject["menu_name"]} </a></li>";

Where is this coming from "$sel_subj"?

<?php require_once("includes/functions.php") ?>
<?php require_once("includes/connection.php") ?>
<?php
if(isset($_GET['subj']))
{
	$sel_subj = $_GET['subj'];
	$sel_page = "";
} elseif(isset($_GET['page'])){
	$sel_subj = "";
	$sel_page = $_GET['page'];
} else {
	$sel_page = "";
	$sel_subj = "";
}
?>
<?php include("includes/header.php"); ?>
<table cellpadding="0" cellspacing="0" id="structure">
    	<tr>
        	<td id="navigation">
		<ul class="subjects">
			<?php

				// 4. Use returned data
				$subject_set = get_all_subjects();
				while($subject = mysql_fetch_array($subject_set))
				{
				echo "<li";
				if($subject["id"] == $sel_subj) {
				echo "class=\"selected\"";
				}
				echo "><a href=\"content.php?subj=" . urlencode($subject["id"]) . "\"> {$subject["menu_name"]} </a></li>";

				$page_set = get_pages_for_subjects($subject["id"]);
				// 4. Use returned data
				echo "<ul class=\"pages\">";
				while($page = mysql_fetch_array($page_set))
				{
					echo "<li";
					if($page["id"] == $sel_page) {
					echo "class=\"selected\"";
					}
					echo "><a href=\"content.php?page=" . urlencode($page["id"]) ."\"> {$page["menu_name"]}</a> </li>";
				}
				echo "</ul>";
			}


			?>
           </ul>
           </td>
           <td id="page">
           		<h2>Content Area</h2>
                <?php
				echo $sel_subj;
				echo $sel_page;
			?>
           </td>
       </tr>
    </table>
<?php require("includes/footer.php"); ?>

When looking at the source do you see the class="selected" ?

 

Try this:

					echo "<li";
				if($subject["id"] == $sel_subj) {
					echo " class=\"selected\"";
				}
				echo "><a href=\"content.php?subj=" . urlencode($subject["id"]) . "\"> {$subject["menu_name"]} </a></li>";

 

If that doesn't work, do this:

					if($subject["id"] == $sel_subj) {
					echo " class=\"selected\"";
				}
				echo "><a href=\"content.php?subj=" . urlencode($subject["id"]) . "\"> {$subject["menu_name"]} </a>";
				echo " subjID: ".$subject["id"]." - getID: ".$sel_subj."</li>"; // debugging

I may have been staring at this code for to long. I don't see a difference. What do you mean "Do you see the class="selected" "?

[CyberShot]

Thank you very much. I spotted it. I didn't think the space after the quote on the echo " class=\"selected\" would make a difference. It actually fixed three problems I was having. So you fixed three in one, Nice shot..

 

Thanks for your help. I appreciate it.

 

Now can you tell me why adding a space after a quote fixed the problem?

[Philip]

Because when it printed, it would print

<liclass="selected"

compared to:

<li class="selected"

[CyberShot]

Oh! I get it! Wow! I never would have spotted that. I knew about spacing from concatinating (spell check) things, but I didn't have any idea that was what was going on here.

 

Thanks for that. That info should come in handy in the future

[Philip]

Yup, whenever you come across that, take a look at your html source code when viewing the page. You'll notice it pretty quick

[CyberShot]

didn't even think to view the source code of the page. Another great idea. Wow, you are just batting them out of the park tonight! LOL
