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>

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
The below code will not display any output as the variable is declared below the echo as PHP gets executed line by line. Is there any way to search for the variable in the whole page and then execute the code?
<?php
include "header.php";
$title = "Test";
?>
header.php
<html>
<head>
<title><? echo $title ?></title>
</head>
You need to learn how compilers/interpreters works. PHP is interpreted language and The binary that lets you interpret PHP is compiled.
PHP run from top to bottom.
so its like
<?php // start from here
echo "$title"; <-- $title is undefined here
$title = "Test"; <-- now you declared $title with value so it goes in memory now
//end
So you need to first check weather $title is set or not than respond according to it
if(isset($title)){
echo $title;
}
According to your logic, I suggest you to use contants like below:
Create a separate file, let's say constant.php and include it on all other pages
<?
define("TITLE", "This is title");
?>
Use it like below:
<?php echo TITLE;?>
Thanks
I have something like this:
PHP code at the start:
<?php
$variable="example";
?>
Then HTML code:
<html>
<head>
<title>Title</title>
</head>
<body>
Then again PHP:
<?php
// code comes here, and I want to access variable $variable here.
?>
And then HTML code ends:
</body>
</html>
Is it possible to do this somehow? I don't want to create another file; I need to do this in this file.
Not Required unless if you are accessing it under functions ( as it will lose their scope)
test1.php
<?php
$var = 1;
//.. your code...
?>
<html>.....
<?php
echo $var; // prints 1
whereas the below code won't work...
<?php
$var = 1;
function displayVar()
{
echo $var; // You will get a notice .. !
}
Just do what you stated above and it will work.
<?php
$variable = 'Hello';
?>
<html>
<head>
</head>
<body>
<?php echo $variable; ?>
</body>
</html>
The above example will display a simple webpage with 'Hello' as the content. This is one of best strength of PHP actually.
try this
echo ($variable);
or
print($variable);
If it is the same file, yes it is possible, unless the variable is in a function. But this is a very simple question, that you could have tested yourself.
<?php
$conn = oci_connect('usr', 'pass', 'host');
$instance_status="command1";
$spacecheck="command2";
$log_apply="command3";
$command=$_GET['name'];
echo $command;
$stid = oci_parse($conn, $command);
--some code--
?>
My HTML Page:
<html>
<title>Status Check</title>
<body>
<b>Spacecheck</b>
<b>Log Application Status</b>
<b>Database Status</b>
</body>
</html>
The above is my code, I intend to assign to $command, the value from the href variable through $_GET. But, when I test this code, $command is not being assigned the value of the variable from $_GET, rather the name of the variable is simply assigned to $command.
Eg, If I click on this:
Spacecheck
This should assign the VALUE of $spacecheck to $command, which is not happening. $command returns '$spacecheck'
How do I do this variable assignment?
You are simply writing $spacecheck. What you need to do is jump inside PHP tags and echo the variable values. Like so:
Spacecheck
or use the php echo shortcut:
Spacecheck
See the difference?
Good luck.
try going the other way around, I mean print from php:
<?php
echo '<b>Spacecheck</b>';
echo '<b>Log Application Status</b>';
echo '<b>Database Status</b>';
?>
You must use PHP open and close tags in order to place PHP code in your HTML page among other things. Try this link:
http://www.php.net/manual/en/tutorial.firstpage.php
Your HTML actually contains the literal string '$spacecheck' in the URL. $variables are only parsed in sections between tags, not in plain HTML.
Try this in your HTML file (which should be called .php) instead:
<?php
$spacecheck = 'foobar'; // (some dummy values)
$log_apply = 'nope';
$instance_status = 'idle';
print("<html>
<title>Status Check</title>
<body>
<b><a href='oraData.php?name=$spacecheck'>Spacecheck</a></b>
<b><a href='oraData.php?name=$log_apply'>Log Application Status</a></b>
<b><a href='oraData.php?name=$instance_status'>Database Status</a></b>
</body>
</html>");
?>
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'); ?>
