PHP - Important!! Is My Logic Sound?? A Question About Include, And Require

I am very confused in between these three terms INCLUDE, REQUIRE, HEADER...

Can anyone tell me the difference between these three terms...

I just want to run a php file in the if condition..

Basically i do not want to open i just want to run ...

for ex.

Code: [Select]
<?php
if(condition)
{
// run mail.php file
}
?>

Hello,


I have a small and annoying problem. Imagine that I have a main folder on my FTP server which has index.php and I then have a php folder for all of my small scripts and an includes folder for misc files. So, for instance

http://www.somedomain.com/index.php
http://www.somedomain.com/php/somescript.php
http://www.somedomain.com/includes/somefile.html

Inside somescript.php, I need to use one of the files from the includes folder, like this for example:

require('../includes/somefile.html');

This is all fine, but the problem is when I include the PHP file on my index.php page. Then I am telling PHP to go one step back to find the includes folder, but the problem is that it only needs to go one step back if it PHP script is not included on some page outside of the php folder. If I run php/somescript.php, there is no problem, but if I include php/somescript.php on my index.php, then there is trouble!

I hope you guys understand what I mean.

Thanks in advance!

PS - I would appreciate if the solution is not about moving php/somescript.php or using full URLs in my includes.

I am using php require to input a page of code.  I am including (require) that file several times within the page.  I am guessing that it executes the file every time, and does not save any page loading time, and in fact probably slowing it down because it has to make the request every time.   Just wanted an expert to confirm or deny my educated guess.  Would it be the same if it were including an html file instead of a php file?

<?php require ("$base_path/main_page_rotation/content4.php"); ?>

Hello all, i just joined today, because am going nuts with php and the include or require statement/function

I want to use them to link to a header. Nothing hard about that , I would say. But my bit of code below just does not work.

I am running them in a test area on my server. Just to be safe The file L2.php is in the same directory/folder ( showing my age).

 

I should  say that am have been programming a while but only using php for about 4 weeks and this normal simple bit of code has me stumped.

 I am building the site in visual studio and atom.

 any pointer would be received with joy

 

The content of L" is also below .

Danler

 

 

 

<?php include_once('L2.php'); ?>

centents of l2.php below

<h3>  line 2   <br><H2>Hello world AM TRYING 6</h2> </h3>

 

I need to include a pagination file in multiple pages or create a custom function but not sure which one to use.

For example:

Code: [Select]
<?php

function test() {
    echo "Hello PHP Freaks!";
}

?>
Or I can create a separate file that echos this statement and include it.

When do you use include/require and when do you create your own custom function?

Hello guys,

I have a question about the logic of OR (||) and &&

I have a form and on the form is asks for hair color

Code: [Select]
<div class="hcenter"><div class="box3">Hair color</div></div>
<div class="box2"><input type="radio" name="hair" value="Black" />Black<br />
        <input type="radio" name="hair" value="Brunette" />Brunette<br />
        <input type="radio" name="hair" value="Blonde" />Blonde<br />
        <input type="radio" name="hair" value="Red" />Red<br /></div>


I grab the post var  like this

$hair = $_POST['hair']; // I actually have it filtered but you get the point

I created this function

Code: [Select]
function check_Haircolor($hair){
if (isset($hair) && $hair != 'Brunette' || $hair != 'Black' ||  $hair != 'Red' || $hair != 'Blonde' ){
Do something here

}

}

But it would not work correctly.. I kept doing the "Do something here...." so I tried the && and it worked (Se below) as expected. I would have bet that the or (||) would have been the correct code..



Code: [Select]

function check_Haircolor($hair){
if (isset($hair) && $hair != 'Brunette' && $hair != 'Black' &&  $hair != 'Red' && $hair != 'Blonde' ){
Do something here

}

}


Why did the && word and not the ||

Thanks,
Dan

I want my PHP code to display and handle a form.

If the form hasn't been submitted it needs to display the form.

If the form has been submitted but the data couldn't be validated then I want to display the same form (with the user's data intact).

If the form has been submitted and the data was validated then it handles the form and prints a message.

The problem I seem to be having is that I have nested conditionals that both need to execute the same code.  I cant seem to wrap my head around it.

trying to use a require but not working properly

Fatal error: require() [function.require]: Failed opening required 'get_extra.php?id=1' (include_path='.')

first thing set on page is.. page is profile.php?id=1
$userid = $_GET['id'];

code is:require "get_extra.php?id=$userid";

what can i do to fix this?

thanks

Just a quick question about including php files on a page...

Let's say I have my index page that is a fully functioning page with all the <html>, <body>, and <head> tags where they should be.  Now I want to include another file, which also has <html>, <body>, and <head> tags.  Would this cause any problems or is it ok to include the second file as is?

Any help is much appreciated in advance...

I have a master file located along the root path that needs to be included in subdomains.  Inside the master file are includes like Code: [Select]
<?php include("../bodyCopy/anyfile.php"); ?> that need to reference the /bodyCopy directory IN THE SUBDOMAIN and NOT along the root.

The problem that I'm having is that the master file resides OUTSIDE of the subdomain on the root (in a '/bodyCopy' directory.

How do I write the PHP include so that files included in a subdomain from outside of the subdomain (on root) search directories INSIDE the subdomain and NOT relative to the root path?

Here's what I mean.

I have this file sitting on the root:  /home/xxxx/public_html/constructfiles/filetoinclude.php

It needs to be included he   /home/xxxx/public_html/SUBDOMAIN/publicfile.php

Then, 'filetoinclude.php' needs to include other files that are he   /home/xxxx/public_html/SUBDOMAIN/bodyCopy/otherfilestoinclude.php

...but, 'filetoinclude.php' is searching along the root path for '/home/xxxx/public_html/bodyCopy/otherfilestoinclude.php' (which does not exist), and NOT within the SUBDOMAIN for the '/home/xxxx/public_html/SUBDOMAIN/bodyCopy/otherfilestoinclude.php' like I need it to.

It appears that PHP will only search along the root path of the included file and NOT the root path of the file in which an include is included.

I'm confusing myself now, but I hope someone can help.

Thanks,

Jet

Hello person who reads this now

I work a lot with <?php include("..."); ?> and I never thought beyond the html I put in there.

In 1 of the include files I have the set-up of a simple vertical html/css menu and on the right next to it
I have an image. However, not every page on my website needs the same image and I probably will change
a lot of them frequently.

Now I was wondering if (and how) I could include a piece of PHP code which does the following:

If the web-url is "page1.php" show "image1.png"
If the web-url is "page2.php" show "image2.png"
If the web-url is "page3.php" show "image3.png"
etc.

This way I only have to change the "imageX.png" in 1 file.

I hope you can help me.

Best regards and thanks in advance!

Hi

I'm in a need of help here, I need to inluded this: "http://site.com/products.php?do=groups&groupid=2"    in a a tpl file. 

Any way that this can be done?

an example would be greatly appreciate it.

cheers

I'm a little confused with the use of absolute paths in PHP.  I've always used relative paths but it's becoming an issue with some of the apps I'm working with and absolute would solve the problem.

The thing is, I'm getting different results in different places and I'm a little confused.

With regular HTML I seem to be able to use / as the root of my site.  So if I do the following...

Code: [Select]
<img src="/images/name.jpg" />
That works fine no matter what page it's called from in the site and no matter what directory that page is in.  I need to be able to do that same thing with PHP.

Now, in my custom 404 page I have the following...

Code: [Select]
if($AddressURL == 'http://www.domain.com/blog/files/filename.zip')
{
header('HTTP/1.1 301 Moved Permanently');
header('Location: /download/filename.zip');
exit();
}

That actually works just fine. If I go to the /blog/files/filename.zip (which doesn't exist) in a web browser it winds up downloading the file at www.domain.com/download/filename.zip as expected. 

Now where I get confused is that include files don't seem to work like that with PHP.  If I do this...

Code: [Select]
require_once('/includes/config.php');

That winds up looking for an /includes folder all the way back at the local server root, not just the web root.  so it's looking for /var/includes instead of /var/www/includes and of course that doesn't end up working.

So, how come the include file paths work differently than regular HTML paths or header redirects in PHP?  Is there any simple way I can always refer to the SITE root no matter what server it's running from?  I've tried playing with $_SERVER['DOCUMENT_ROOT'] but it only seems to return the root of the current document, not the root of the whole site.  So if I use it within a php file located in /var/www/includes/test.php it considers /includes the root which is not what I want.

Any information would be greatly appreciated.  Thanks!

First off, I am new to PHP, and want to learn it, but it seems very complicated. Where do I begin?

I found a script online for a contact form and I am having trouble making it work for my needs. I wanted to include a phone number field in the email message. This is what I have so far for the PHP, but it does not include the phone field in the body of the message. Everything else works fine. Apologize in advance if this message has been posted many times before.


<?php

$post = (!empty($_POST)) ? true : false;

if($post)
{
include 'functions.php';

$name = stripslashes($_POST['contactname']);
$email = trim($_POST['email']);
$subject = "New Message from your website"; 
$message = stripslashes($_POST['message']);
$phone = stripslashes($_POST['phone']);



$error = '';

// Check name

if(!$name)
{
$error .= 'Please enter your name.<br />';
}

// Check email

if(!$email)
{
$error .= 'Please enter an e-mail address.<br />';
}

if($email && !ValidateEmail($email))
{
$error .= 'Please enter a valid e-mail address.<br />';
}

// Check message (length)

if(!$message || strlen($message) < 15)
{
$error .= "Please enter your message. It should have at least 15 characters.<br />";
}


if(!$error)
{
$mail = mail(WEBMASTER_EMAIL, $subject, $message,
     "From: ".$name." <".$email.">\r\n"
    ."Reply-To: ".$email."\r\n"
    ."X-Mailer: PHP/" . phpversion());


if($mail)
{
echo 'OK';
}

}
else
{
echo '<div class="notification_error">'.$error.'</div>';
}

}
?>

How can I use an include file that has a list of links in any directory at my website without breaking those links?

You can see it in action here...

The links in this directory work...

https://www.billelgin.com/primary-directory/

The links in this directory (being created from the same include file) do not work...

https://www.billelgin.com/primary-directory/subsection-one/

Obviously the problem is the include file is being called from different directories, so it's breaking the relative path links in the include file, but what can I do to fix it?

You can download the example directory structure here...
