The php variable is not displaying the result.
<h2 class="bold"><? echo ${"application->client->s_MEMBERCLUB_STATUS_{$i}_NAME"}; ?> Member</h2>
You can use
<?php echo $something; ?>
or
<?= $something; ?>
Which is the shorthand.
If you want to use the original code, although it is discouraged, you can check out how to enable it here:

I currently have a php which echo my html template.
However in that HTML template there is another echo which calls from another php script.
Just wondering how do I do that? Because once I echo my html template the other it doesn't seems to echo my content from the other php script.
HTML TEMPLATE
<php? $html = '<span>name:<?php echo $name; ?></span><span>email:<?php echo $email; ?></span>' ?>
CONTACT TEMPLATE
<php? $name = "hello world"; $email = "hello#world.com"; ?>
I can see what you're trying to do, and it's a simple error. You can't escape php like that whilst inside setting a variable.
Also, I must add that you are declaring php incorrectly.
This is preferred
<?php
not
<php?
So make sure for your contact template you use the correct tag.
Also to include a file you have to call it/require it.
Back to the original question - Here is your method
<php? $html = '<span>name:<?php echo $name; ?></span><span>email:<?php echo $email; ?></span>' ?>
Here is the correct method
<?php
require('contact.php');
$html = '<span>name:'.$name.'</span><span>email:'.$email.'</span>';
echo $html;
?>
First I created the variable. And when doing so I insert the existing variables by escaping the php. Only once this final variable is created do I echo it.
Hope this helps you on your way.
Try to use include. The include statement includes and evaluates the specified file, in this case - your template.
Just Concatenation
<?
$html = '<span>name:'.$name.'</span><span>email:'.$email.'</span>';
?>
Change the tags from <php? ?> to <?php ?> in your script
Let's say I've got 2 files. 1 is common which loads all the design and stuff and one is index.
What I want to do is set a $ in index like this:
<?
$SubId3 = 'test';
include "../../common.php";
?>
Then in common I want to have something like
<?=$SubId3; if (empty($SubId3)) { echo 'homepage'; } ?>
I cannot seem to get this working. Meaning if I set it up this way. The index will never show "test".
What am i doing wrong here?
I want to do this since only certain files will contain the string $SubId3, to test some things on certain pages and not others (by adding $SubId3 = 'test'; to that particular file)
Note that <?= is short-hand to output something (think of <?= as <?php echo) and not to execute any other sort of logic or code.
However, it is possible to use the ternary operator this way:
<?= empty($SubId3) ? 'homepage' : $SubId3; ?>
This is basically equivalent to this:
<?php
if (empty($SubId3)) {
echo 'homepage';
}
else {
echo $SubId3;
}
?>
So the <?= short-hand should only be used to pass one simple variable or a ternary expression to it; everything else should use the common <?php tag.
Here's a test case for Alex (in the comments) because I can run the above code just fine with PHP 5.4.12, but he seems not to be able to.
common.php
<?= empty($SubId3) ? 'homepage' : $SubId3; ?>
index.php (visit this file then)
<?php
$SubId3 = 'test'; // <-- Comment this out for the "homepage" output
include 'common.php';
i think this
<?=$SubId3; if (empty($SubId3)) { echo 'homepage'; } ?>
should be
<?php $SubId3; if (empty($SubId3)) { echo 'homepage'; } ?>
<?=?> is short for <?php echo?>
This wont work:
<?=$SubId3; if (empty($SubId3)) { echo 'homepage'; } ?>
If you want to print some stuff, you have to use only the variable, in one block and the IF on another.
<?=$SubId3?>
And:
<?php if(empty($SubId3)) { echo 'homepage'; } ?>
Hope this helps...
Try
<?php
/* echo $SubId3; */
if (empty($SubId3)) {
echo 'homepage';
} else {
echo $SubId3;
}
?>
Consider using different style of coding.
In PHP you have generally three variants:
PHP code only
HTML files with just some echoes
Intermixed PHP and HTML
In first you use echo to output every single bit of the HTML.
Second means you include a PHP script at the top of your HTML file and call appropriate functions / insert text into the template. Just so you can edit your HTML separately from your PHP.
Third makes for sometimes unreadable and complex code, but is fast to write.
<?php if($something) {
while($otherthing) { ?>
<B>text=<?=$index ?></B>
<?php }} ?>
Just a food for thought.
I found the answer guys, thanks for all the help.
I needed to set it in the PrintHeader like this:
<?
include "../../common.php";
printHeader('BlogNr1', 'BlogNr2', 'BlogNr3');
?>
And the index had to look like this:
<?
include "../../common.php";
printHeader('BlogNr1', 'BlogNr2', 'BlogNr3');
?>
Somebody on skype helped me. thanks anyways guys!
I'm looking for something much like the Using PHP variables inside HTML tags? question, but a little different.
In my case, I'd like to use code ore like this:
$somevar = 'a test';
include("file.html");
and file.html would contain
<b>hello, this is {$somevar}</b>
The problem is that it just prints hello, this is {$somevar}.
How can I make the HTML read the vars in the included file?
echo "<b>hello, this is {$somevar}</b>";
or
<b>hello, this is <?=$somevar?></b>
or
<b>hello, this is <?php echo $somevar; ?></b>
or
<b>hello, this is <?php print $somevar; ?></b>
You need to include the variable defining program, in the other program wanting to access it.
Example:
Say test.html has $somevar.
in file.html you do,
<?php
include('test.html');
echo "<b>hello, this is $somevar</b>";
?>
<?php
include "stuff.php";
$somevar = "test";
?>
<html>
<body><p><?php echo($somevar); ?></p></body>
</html>
vSlider - in WordPress I'm using the function supplied in the FAQs:
<?php if(function_exists('vslider')){ vslider('vslider_options'); } ?>
And I'm trying to do this. So its knows to get the post-ID as its name. But its not working.
<?php if(function_exists('vslider')){ vslider('<?php the_ID(); ?>'); } ?>
You cannot nest <?php ?> inside an already open <?php ?>. That is unsupported and syntactically invalid. Just call the function in place.
Apparently, the_ID() is one of those Wordpress functions which prints to the output buffer without returning its value. To get the id returned where it can be useful in a function, use get_the_ID() instead.
<?php if(function_exists('vslider')){ vslider(get_the_ID()); } ?>
The syntax issue becomes more obvious when expressed as properly indented code.
<?php
if (function_exists('vslider')){
vslider(get_the_ID());
}
?>
Yes you can do this by removing the php tags
<?php if(function_exists('vslider')){ vslider('<?php the_ID(); ?>'); } ?>
should be
<?php if(function_exists('vslider')){ vslider(the_ID()); } ?>
and your the_ID() function should return a string at the end
I'm calling a function like this:
<?php print get_thumbnail('http://url.com/?skin=rss'); ?>
Being a php newbie, I'm wondering if there is a way to change the http://url.com part based on a custom metadata I have set up in Wordpress. So I guess it would look something like this:
<?php print get_thumbnail('<?=$video_src?>/?skin=rss'); ?>
Is something like this possible?
Yes, you have the right idea, you just don't need to re-open PHP tags since you're already inside some. You can use . to concatenate (join together) the value of $video_src and "?skin=rss".
<?php print get_thumbnail($video_src . "?skin=rss"); ?>
Try this:
<?php print get_thumbnail($video_src . '/?skin=rss'); ?>
Keep in mind that <?= $foo ?> is shorthand for <?php echo $foo; ?>. <?= ?> won't be expanded in strings, but you can achieve something similar using double quoted strings:
<?php print get_thumbnail("$video_src/?skin=rss"); ?>
Yes, except within PHP, you don't need to enter the PHP tags again.
<?php print get_thumbnail($video_src . '/?skin=rss'); ?>
