I was wonder if there was a way to take the html results that was created from a php script and take that html code generated and put it inside another php script?
The problem I'm having is that I'm working inside a huge php script and I always have errors when I'm working inside it. I want to make additions to the code, but it never works. Files aren't opening. However, when I work outside it and within the same folder, my code works.
So I'm thinking if there's an "Iframe" for php code or maybe I should use an iframe instead?
Can't you just use include or require to include the code from the other script?
Create a function myFunction to output whatever html you want.
Put that code in a file whatever.php
Call include('whatever.php') from your other PHP file
Call myFunction() and your html will be outputted.

I have php editor.The php code in the editor go to this php variable: $redux_demo['opt-ace-editor-php']. How can I write this variable to php file?
For example, I insert the css code come from css editor like this:
echo '<style type="text/css">'.$redux_demo['opt-ace-editor-css'].'</style>';
Also, <?php tag may can be use top of code in editor or may not.So, the code must work in two scenerio.
So, I wonder can I use <?php tag after another? Or can I use <?php tag in echo function?
PHP code is different from those code running inside the browser. PHP code runs in your server.
If you are sure you want to write code into PHP file. Try use:
file_put_contents("path/to/php/file.php",$content);
And make sure, for every PHP file, a tag should be put at the beginning, like:
file_put_contents("path/to/php/file.php","<?php\n$content");
BTW, be alert and careful when write PHP file dynamically, it may introduce security issue by doing this.
I'm attempting to make a template file for a CMS that I'm making where the template file can contain variables like {username} as regular text that get replaced when the page gets included on the index.php page.
Example:
Index Page:
<?php include('templates/123/index.php'); ?>
templates/123/index.php page
<?php include('header.php'); ?>
Welcome {username}
<?php include('footer.php'); ?>
I've tried several methods; however, always run into problems because the page I'm trying to change the content on includes PHP code. Every method I try either 1) messes up because the opening and closing of PHP tags within the document OR 2) just echoes out the PHP code in the document. Is there any way that I can still achieve this? Maybe even with a class of some kind? I just want to be able to achieve this safely.
I will also be using this to where custom variables like {content1} get replaces with a php code that will be ioncubed that retrieves the data from database for content located in column1, same with {column2} {column3} and {column4}. I'm just trying to make the creation of templates extremely easy. (so I'd like to make the code work for that as well)
My preferred method of doing stuff like this involves starting my code with:
ob_start(function($c) {
$replacements = array(
"username"=>"Kolink",
"rank"=>"Awesome"
);
return preg_replace_callback("/{(\w+)}/",function($m) use ($replacements) {
return isset($replacements[$m[1]]) ? $replacements[$m[1]] : $m[0];
},$c);
});
Two steps I suggest
Load the result of your file "templates/123/index.php" into a variable. see this link for how to do it assign output of execution of PHP script to a variable?
use strtr() function to replace your placeholder i.e {username} with actual values
I think this will server your needs.
I've created my own templating/viewing engine to use with Codeigniter. In it I'm able to specify certain css/js files to use with a specific view. I assign the file names in an array, which will then get looped through while echoing the necessary <link href="X"..., <script type="X"..., etc for the respective file type in the header file of the template.
The problem is that I can't seem to use the resources I'm trying to include. The CSS/JS files aren't working even though they're being included and embedded and everything looks right in terms of the syntax in the HTML source code.
My theory is that because I'm using echo to actually print the link/script object into the HTML, that it's actually not really an object that HTML can recognize? Kind of like trying to echo an object in PHP - it doesnt work.
Any advise?
It does not matter if you use plain HTML of php generated code. For the browser it is all the same.
You need to check your source code, and check if the scripts you include are accessible. So copy/paste the src="blabla" from your source code from your browser, and paste it in the address-bar and see what happens.
It is definitely not PHP's fault.
I'm learning all this web programming stuff after years writing .EXE Windows programs so bear with me.
I developed a basic .php and mysql website that works fine.
But I went to add javascript code to my index.php and I don't think the javascript code is executing.
My index.php has the form:
<?php
require_once blah blah
call_my_php_functionBlah();
?>
Then I added this code inside the php blocks of the '<\?\php' and "\?>" as follows:
<script type="text/javascript">
// some known-good javascript code that displays an image
</script>
Nothing showed up.
So I thought "ah-HAH, I blew it, all I need to do is -- move the javascript code outside
of the php block, at the bottom of index.php, and surely I'm good to go."
And still, Nothing showed up.
I checked the source of my 'known-good' javascript code and it said 'embed this javascript code
in your HTML file' so I thought "wow, I guess I need an index.html or something here."
So my questions:
1) should my index.php be able to run the javascript block of code?
I'm guessing 'No because index.php executes on the server and javascript runs on the client machine.'
2) How should I architect this if I want to keep my index.php, whose code works fine and I don't want to mess with it?
I'm thinking that this is an extremely basic client/server, php and javascript script organization issue that every web programmer knows how to handle, but like I said, I'm new to all this. I read in the archives about .htaccess etc. etc. but I
bet there's an easier way, and I'm not sure if the stuff I read applies.
the file name extension is completely irrelevant
PHP executes on the server and doesn't care at all about any Javascript
code inside <?php ?> tags must of course be valid PHP code to be executed by PHP
your browser receives whatever the result of your PHP execution is
you can use PHP code to output Javascript or simply have Javascript on the same page outside of <?php ?> tags
only whatever the browser receives matters, so use View Source
look at the browser's Javascript Console to debug client-side Javascript problems
Then I added this code inside the php blocks of the '" as follows:
Dont add your script inside the php block bring it outside php block.
After you are done with script you can reopen php block and write php again
index.php can run javascript, just that You need to echo the javascript code to put it in the page.
Anything that appears inside your php open/close tags has to be echoed or printed to be rendered to the html page. Anything outside your php open/close tags should appear in your html page but whether it works correctly or not is another matter not necessarily related to your php. The php interpreter doesn't run your javascript code, however, so it can't just sit inside your php tags.
Javascript will run inside .php file.
But you have to write outside the tags.
Eg:
index.php
<?php
echo "Helloooooo";
?>
<script>
function TestingMyFirstScript()
{
alert(1)
}
</script>
Javascript will execute in a PHP file but not inside of a PHP block. It executes in the server, yes and anything coming from PHP should be printed out to see. You should have the JS code outside of the PHP block and it can be anywhere in the page e.g.
It depends how to mix/match the code but of course keep it clean and easy to read (and debug).
<?php
// code here
?>
<script type="text/javascript">
// JS here
</script>
<?php
// some more code here
?>
Answer to both of your question is that you dont have to create a separate html file to execute your JS code. You can have HTML, JS, and PHP code in the same file. PHP code inside the PHP tags will be processed on the server and replace with HTML. The server generated HTML will be combined with other HTML present on the .php file and sent to the browser as one HTML.
There must be some error in the JS code which is causing the script to fail.
<?php
require_once blah blah
call_my_php_functionBlah();
?>
<script type="text/javascript">
// some known-good javascript code that displays an image
</script>
<?php
// other php code
?>
Most of the above comments should help you with your PHP + JS problem. However, if you are still getting errors with your output, try using:
alert("breakpoint 1");
//some code
alert("breakpoint 2");
throughout your Javascript function (it will show you where the code is failing). Good for beginners debugging. Also check out http://www.jslint.com/
Before I ask this question I must point out that I have tried to search for EVERYTHING!
My question is how can I run javascript from an external file instead of inside my php / html. What I'm trying to do is.
function ClearForm() {
document.form.message.value="";
}
function comeBack(){
if (document.form.message.value == "") {
document.form.message.value="What's on your mind?";
}
}
I have included<script type="text/javascript" src="javascript.js"></script> in the <head> and I have a file in the root called javascript.js and my php file is in the root too so that shouldn't be the problem! But how do I run that pieces of code you see above in the javascript.js file instead of in my php file. It work's fine if I have it in the php file but I want to separate things!
I have also tried to give the form / input field an id and then use getElementById in the external JavaScript file.
But as you can see and hear I'm kinda new to JavaScript so I'm apparently doing something wrong here.
If the above code is the only thing in your Javascript.js file, then you need to call the functions to run the code.
You've included the external Javascript file correctly - however, because all of your JS is included within functions, these function/s must be called before the code will run.
A call to 'ClearForm()' or 'comeBack()' from within your PHP file should run the code.
That JS file will have to be in the same folder as your PHP page.
Test whether the file is found or not by adding this line at the top of the js file
alert('js file found OK!');
document.form is an array, so if you only have one form use:
document.forms[0]
Also depending on which browser you use, find and install some Developer Tools to help you identify these errors.
You have declared those functions in the <head>. All fine.
The question is when do you want to call/run those functions?
If you simply want to run them at the end of the page, then you can add another external javascript file and include it using <script src="my_external_file.js"> right before the </body> tag.
Otherwise, you have to declare onXXX handlers, like onLoad() for the document, onClick() for certain elements, onSubmit() for forms, etc. These, too, can be declared in an external file, but specified after the relevant elements are loaded.
