I'm a newbie to Facebook app development. It almost works when the page liked.php is shown (it's shown when a user liked the site), the PHP code is displayed as text output.
my liked.php code:
deleted for privacy reasons
?>
Here's the output(it's shown as blank text):
I simply don't know why. Even the error_reporting(E_ALL); doesn't show anything. Simply blank text output. I use the newest facebook php sdk.
I guess the problem is not in the code but in the configuration of your server. You need to tell the server to execute the php code instead of displaying it.
Sounds like you either don't have PHP installed or you're not using a file extension which invokes the PHP engine - is your file called [Blah].php?
Some things to check:
You're serving the file from a web server (not locally)
The server has PHP installed
Your webserver is configured to use the PHP engine to handle the file type you're using (usually .php or .php4 or similar)
creating a new file with just <?php phpinfo(); ?> and serving it should give you lots of info about your PHP install.
If you have access to the server, you should be able to run PHP from the command line/shell

I can't find a way to run php on Visual studio code, Does anyone know how?
Duplicate:
Yes it is but a little bit different from here.
Steps:
I followed below steps to configure php in VS Code.
Configure PHP linting in user settings
Install Php Debug extension in VSCode
Then configure php.ini file
Create a external php file in root folder
add <? echo "My First PHP site in VSCode."; ?> in external php file which I created now
In my index.html file I referenced my php file like:
Run my web server apache using xampp control panel
Build my project and run it on web browser it shows me nothing.
Also when I open dev tools of my chrome browser its shows me my php code of index file commented. why? I don't know.
Question:
What I am doing wrong in my above steps to configure php in vs code. Please explain me in easy steps so I can easily achieve my goal. Thanks in advance.
Looks like you in fact don't want to run PHP from Visual Code, but instead you're trying to get PHP to work at all.
add in external php file
which I created now
You're using short tags and that's ok, if your configuration allows it, however I would recommend using explicit PHP tags: <?php echo "My First PHP site in VSCode."; ?>
In my index.html file I referenced my php file like:
There's the problem. You're placing PHP code in a HTML file. PHP code in HTML files won't be (at least by default) executed. Change the filename from index.html to index.php.
That should do it.
i was setup my server, unfortunately the php page not loaded in the browser. Looking at the view source pages, i see my php codes. I using centos and install cpanel.
What usually reason for the problem?
It means PHP is not running.
Have you tried reaching localhost in your browser? Generally you should see the PHP index file, which tells you if the server works or not.
A few possibilities :
Is your file in the proper root folder? Is is accessed via localhost (not file system!)
is your file in .php (ex. NOT .html)?
Are you using full <?php ?> tags? Some server configs won't recognise <? ?>
Problem Description in Brief:
PHP script seems to work on my local web server when I 'include' it from the footer tag of my index.html file, but does not work when I upload it to my website. Note that I have made sure that all paths are correct, and that the script file has its own php tags, etc.
Problem Description in Detail:
Yes, I am new to PHP scripting, and yes, variants of this question have probably been asked before. The answers to a few of the questions I have read have noted the path of the php script files to be incorrect. I have checked all paths and confirmed that they are indeed correct (including those on the web hosting server). Furthermore, I have been successful in getting the script to work on my local server running Apache2 with PHP5, but have not been successful when uploading it to my website.
Essentially, I am trying to implement a hit counter script which I have acquired from a Stack Overflow post labelled Visitors counter for simple web sites like Vinaora. The code that invokes the php script looks something like this....
<footer>
<!-- Execute Hit Counter Script -->
<?php include($_SERVER['DOCUMENT_ROOT'].'/php/hitcounter.php'); ?>
</footer>
For the likes of me, I cannot figure out why it does not work on the web hosting server. I have tried other combinations of invoking the script like,
<footer>
<!-- Execute Hit Counter Script -->
<?php include('./php/hitcounter.php'); ?>
</footer>
and,
<footer>
<!-- Execute Hit Counter Script -->
<?php include(dirname(__FILE__).'/php/hitcounter.php'); ?>
</footer>
All combinations seem to work on my local web server, but not on the website! Also note that, I have no problem invoking other PHP scripts using other methods (even on the web hosting server), eg.
<form id="form-query" onsubmit="this.checkValidity();" action="./php/contact.php" method="post">
Any advice/suggestions would be appreciated.
Do you get any PHP error?
First of all, you need to activate error reporting.
Put this before including your file
ini_set('display_errors',1);
error_reporting(-1);
PHP should tell you what's happening.
If you don't see anything, change the filename index.html to index.php and try again.
Maybe be you have used "\" in your include path
Wrong:
<?php include 'includes\header.php'; ?>
You should use "/" to work.
Current:
<?php include 'includes/header.php'; ?>
sometimes it might be dues to casing. check if you you uppercase in naming. on some servers Index.php is not equal to index.php
You might try pasting the "include" code directly into the calling code. Maybe it's the included code itself that's misbehaving...
You are doing completely incorrect thing in the first place.
PHP script seems to work on my local web server when I 'include' it from the footer tag of my index.html
is just totally wrong
There is no such thing as embedding php file within html file (aside from mod_rewrite ...).
For PHP script to be interpreted you must have it (in 99% of cases) with php suffix. This way you allow PHP to distinguish it from regular PHP and send to php interpreter.
Put simply - create this file (a.html):
<body>
abcd<?php echo 'efgh';?>
</body>
and see the result in your browser - use .../a.html
What do you see?
abcd
and not
abcdefgh
On top you always have to have php not the other way around. Solve this or update your question if incorrect.
I have a form where it request name,email,zipcode. However the problem is that. when you click on submit. it ask you to open the file it doesn't go to the script.
The website is http://childcarelv.org/newsletter.html
PHP isn't being handled by your server. Instead, it is just being output straight to the browser.
This is a server configuration issue.
Your server is configured with the correct MIME type (it is returning application/x-httpd-php), but isn't set up to actually use PHP to process it.
Since you are using Apache, read the configuration instructions here: http://www.php.net/manual/en/install.unix.apache2.php
Looks like you might be hosting with ipower.com. If that is the case, this is an issue for them to solve.
From your description it seems that server is not able to execute the php script, and thus gives it as download to the client.
You should try to put the following code in a file named testphp.php and place in your public home directory and go to the page to see if php extension is mapped to the php module on your server.
<?
phpinfo();
?>
This is just to verify/prove that there is nothing wrong in your script, and even a simple test script won't work.
I have a quick question that I can't figure out. I've tried searching Google and following examples, but I can't find anything.
I have an HTML form that I'm trying to process with a PHP file, but when I submit the form, it merely prints the source of the PHP file, it doesn't execute it. If I run the PHP file by itself (not indirectly through the HTML button), it works fine.
HTML form header:
<form id="registrationform" name="registrationform" method="post" action="processregistration.php">
Submit button:
<button type="submit" value="Submit" >Create</button>
The PHP form is just <?php print "Hello"; /?
Again, it runs fine if I just run the PHP file, but prints the PHP file (doesn't run) when it gets called through the HTML form.
Any help is appreciated.
edit-Running locally through Coda
edit-Here is the output that I'm getting:
Output when the PHP is called through an HTML action:
</php
print "Hello";
?>
Output when I run the PHP directly through Coda:
Hello
I had the same problem and just fixed it on my coda version 1.7.4
I installed MAMP on my mac and set up the apache path under MAMP preferences to the folder where my sites are located;
/Users/yourUserName/Sites
this points MAMP's 'http://localhost:8888' address to your sites folder, if you paste that on your browser you'll now see your sites folder's content in the browser.
then, all you do is point the local site's connection settings to the site you are testing;
I was going to post an image, but I'm new to the site and wasn't allowed.
Under my site's preferences i set up the addresses as follows;
Root URL : 'http://localhost:8888/yourSiteRootFolder/'
Local URL : 'http://localhost:8888/yourSiteRootFolder/'
Remote Root : /yourSiteRootFolder/
Local Root : /Users/amartinez/Sites/yourSiteRootFolder/
I hope this is related to the problem you're having and helps you fix it.
Line #19 from Coda 1.6 Release notes:
Coda no longer tries to locally
preview a remote PHP file while
editing/previewing
Listed under "Improvement" - doubt they brought it back for the 1.7 release.
I'm running Apache2/PHP5 10.5.8 OS X (no problem reproducing your issue with Coda)
Even when running my form.html and post.php files from /Library/WebServer/Documents folder.
My sample files work fine in the Apache env....I just needed to run them through Coda to "break" them. :-)
Are you sure the html file and the php script are on a server with php support enabled?
I've never used Coda, but you need to be running it through a server (e.g. Apache + PHP). You cannot just open the file itself within Windows.
Try looking at xampp as a quick server for testing.
If it works properly, you should be viewing the PHP file on something like http://localhost/test.php instead of file:///something/test.php.
This may be because you don't have PHP installed on your server. I would check to make sure that your hosting package included PHP, pre installed.
Here are some resources to get you started with that, if not installed:
http://www.thesitewizard.com/php/install-php-5-apache-windows.shtml
http://www.php.net/manual/en/install.php
http://www.w3schools.com/PHP/php_install.asp
Edit: actually, I think I may have found it.
If you look at the starting PHP tag, you have a slash instead of a ?. If that's in your script, just change that to <?php. But it may not be, it could be that's just question format-ing.
