Problems with PHP 'include' - CSS -tricks (1)Anonymous


I try to include a PHP file with the following example in a Div

<?PHP including "";?>

But it doesn't work. I tried it too

<? Php include "{$ _server ['document_root']}/path/to/file.php";?>

And you guessed it, Nuttin.

Does the file to be contained does the word echo need <?PHP or am I doing something else wrong?

Thanks very much!

You cannot/should insert a file via HTTP on a server.Then it is already processed by the server so that you cannot use the code.

Use only unprocessed files that are in the same environment, with the relative path being used.So never add a domain name (hard coded or in other ways), so something like:

<?Php including "/path/to/file.php";?>

Greetings Senff,

I tried that without success. I had how how

<div> & lt;? php include "/new/test/cform.php";? & gt;</div>

And nothing can be seen within the div.

Use only unprocessed files that are in the same environment.

Could you please explain this? I understand that an absolute way here is not useful and that a relative way is, but I am still blurry that I am "processed on the server and why this makes the code unusableExamples seen that use the absolute way, even though I followed their instructions and went to Zilch, although others said it worked for them. I am too green with all of this to know BS from Brilliance.

In addition, I don't know what happened to my description for this.

I understand that an absolute way here is not useful and that a relative way ...

An absolute way is not "useless"."{$ _Server ['document_root']}/path/to/file.php"is an absolute file path becauseIt starts from the root of the file system. A relative path begins from "somewhere else", such as in the current directory. For example, if you usecontainFrom your document -root directory then"{$ _Server ['document_root']}/path/to/file.php"And"Path/to/file.php"will point both in the same place (however"/path/to/file.php"wouldnot).

just to clarify things is not a file system pathIn general.

If"{$ _Server ['document_root']}/path/to/file.php"Does not work, then the most likely explanation is that it is not the right way and the file is actually saved elsewhere.contain, attempt

$ path = "{$ _server ['document_root']}/path/to/file.php"; var_dump ($ path);

... to see what the full path dissolves.

Also,contain WilleThrow a warning if you do not find (or access) the file you request. Check your error log.

Use only unprocessed files that are in the same environment

What Senff means is when it tries to try itcontainSomething (e.g. a PHP file) via a URL is often the case that the file has already been executed on the other server: you will receive the PHPein browser).

It is the part of its advice that is more importantunsureusecontainWith a URL because it enables a different server control from you. Example if youclose '';There is nothing that prevents another server from giving themMUsticious_database_injection.phpinstead of this.

Your installation of PHPshould beConfigured to prevent URL, comprises completely,*Since it is also used as an attack vector: If someone breaks into your server, he only add a lot of malicious scripts and additional code, but only adds one line (which you notice much less): something like that asIntegrate '';

* Check your PHP.ini file or ask your hosting company.

Greetings Traq,

I tried every variation to include itthis forminthis page(where the box is with the thin black edge) and tried to use it

<? php $ path = "{$ _server [" document_root "]}/form-Test/cform.php";
var_dump ($ path);?>

Nothing works. Is it possible that it is a Z-index matter or an orientation in the form itself, which leads to the form of the form in the page?

In addition, I meant under "absolute path" to enter the complete URL, e.g. I know that it is not a file system path, but a path to a file on a server.

Best regards.

The page on which you want to insert the form is an HTML page, not a PHP.Therefore, the code of the PHP term is never executed.

Greetings Alan,

I thought that was the way to do it and tried it, but I had it too<? php?>Around the HTML what the problem caused. I was new to all of this and had not worked for some time while trying to create a contact form from scratch, I forgot how Simp0le was and thus the question.

However, I remember that<? php?>Did you also have to be placed within the side?

Okay, I displayed the form on the page, but I get the following warnings/errors:

Maybe this is something that has to look at @Untraq-E-ED because he built the tutorial for the shape?

My idea is there a conflict with the UTF-8 and an HTML that is included in the CFOR on the index page and in the CFORE itself?

Many thanks to everyone in advance.

They try to import/absorb PHP code to your page, which is more than just the form -in fact, it is an entire HTML page, including all of its tags such as HTML, head, body, etc.

(go to display the source)

This is probably the reason why she has already received the "already sent" reports ".

What you have to do is to includeOnlyThe code for the form, so that the .php file you want to include, should not contain header or the like.

Edit cform.php and remove everything that comes before and according to the form (everything beforehand<Formand everything afterwards</Form>).

@SenffJust to get you up to date,Here is what we work with.

@Michael1961, now, if I understand correctly, include the class and build the formlikewisePage (thecform.phpPage) and then try to includeThePage onOthersBook page.

This assumes that at the end we are produced a lot from the HTML Markup (this is the problem that has talked about the Senff), and - because they are theirsIndexPage has already sent the output to the browser before trying to enter the contact form.Starting the session does not work (these are the "Headers already sent" error messages that you receive).

Our test pageis a complete "independent" page. If you want to insert the contact form as part of aandersYou can use the same PHP methods (neuer contactMichael1961 ($ _post);Present<? = $ Contact Form-> html markup ();?>) on this actual side.

If you give me the content of yoursIndexPage, I will help you to set it up from there.

In addition, I meant under "absolute path" to enter the complete URL, e.g. I know that it is not a file system path, but a path to a file on a server.

Actually, no, that is the misunderstanding that I would like to point out: are a URL and a file system pathcompletely different things. A URL could beAssigned*To a file system path (e.g. from your server), but in and of yourself are not related things. A file system is looking for files on your computer (server). A URL localizes things (typically) on the Internet.

* A typical example: if Apache receives an inquiry for looks in itsDokument RootDirectory for a file under "Path/File.php". The actual file path is something like/Users/your-name/ other cases, the URL may have no connection with the actual location of the file (e.g.

This is a huge conceptual stumbling block for almost everyone. Because they look similar and because (often) serverYetGive a rather literal assignment for real files through.contain), They are forced to understand the difference.
