Hi I'm trying to get a piece of html to only show on the main page which is http://www.domain.com/ ... I wrote the code below but it doesn't work the HTML is showing regardless of the page, am I missing something
<?php
$hweb .= 'http://' .$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
if ($hweb == 'http://www.domain.com/'):
?>
<div style="margin:0 auto;">
<div style="float:left">
<?php endif; ?>
First of all - please change
$hweb .= 'http://' .$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
into
$hweb = 'http://' .$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
$hweb may be initialized somewhere before.
Second:
As long as you request 'http://www.domain.com/somename.php' your if condition will never get executed. REQUEST_URI will always hold '/somename.php' except you use some url rewriting.
Third:
Make sure all calls go to 'http://www.domain.com' and not to 'http://domain.com'. Subdomain configurtaions sometimes are very complicated.
At the risk of getting it wrong again..
Why not initialize a variable in the main file before including the header
<?php
$mainfile = true;
?>
then in the header
<?php
if ($mainfile===true)
....
This way the main file can be called anything and be placed anywhere.
Solution 1:
If the above code is written inside 'http://www.domain.com/index.php' file then it may work fine.
Solution 2:
else make sure that $hewb is set with null value earlier b4 this code so that ".=" would not add extra value b4 'http...'.
Now
$hweb = '';
echo $hweb .= 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'];
That is because the the HTML is inline in the php file but outside of the PHP tags. You can simply echo the HTML inside the if.
if ($hweb == 'http://www.domain.com/')
{
echo '<div style="margin:0 auto;">';
echo '<div style="float:left">';
}
or if you have lots of HTML you could do it like this
<?php
ob_start();
?>
<html>
<body>
<p>This HTML only be echoed </p>
</body>
</html>
<?php
$hweb .= 'http://' .$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
if ($hweb == 'http://www.domain.com/'):
{
ob_end_flush();
}
else
{
ob_end_clean(); // Probably not needed
}
?>

I downloaded this code:

$bg_img = explode(" ",$image);
$src = substr(strpos('"',$bg_img),strlen($bg_image)-1);
echo "<div style='background-image: url(".$src.");' ></div>
<?php

I'm having problem with the start:
$image = ImageClass::getImage('bg.jpeg','myTitle');
$bg_img = explode(" ",$image);
$src = substr(strpos('"',$bg_img),strlen($bg_image)-1);
echo "<div style='background-image: url(".$src.");' ></div>
I want to put a picture as background, but it isn't happening. What's wrong?
Changed with the answer:
<?php
echo "<div style='background-image: url('/bg.jpeg');' ></div>";
?>
<?php
/*
*** OPTIONS ***/
// TITLE OF PAGE
$title = "ARQUIVOS PROPAR";
// STYLING (light or dark)
$color = "dark";
etc..
No need for all that,
What you desire to achieve is much simpler.
Assuming this code is inside index.php and your server's directory structure:
/some-folder/
/index.php
/bg.jpeg
Simply link it as its done in plain html —
<?php
echo "<div style=\"background-image: url('/bg.jpeg');\" ></div>";
?>
If you wan't it do be dynamic, i.e, image files's name is inside a variable then,
<?php
$my_image = 'bg.jpeg';
echo "<div style='background-image: url($my_image);' ></div>";
?>
Update:
Important Tip: All programming languages are executed line-by-line, this tip applies not only to PHP, but also HTML Learn More
Assume for example, your page's html structure returned to the browser is as provide below and you want to apply background to body tag
<html>
<head><head>
<body>
<nav>Some dummy navigation</nav>
<div>welcome to my website</div>
<footer>Copyright</footer>
</body>
</html>
Simply copying and pasting my code to the top of page will result in
<div style="background-image: url('bg.jpeg');" ></div>
<html>
<head><head>
<body>
<nav>Some dummy navigation</nav>
<div>welcome to my website</div>
<footer>Copyright</footer>
</body>
</html>
But that created a empty div tag at the top of html output, i wanted it to apply background to by body tag instead !!!?
— This happened because echo is used to send output to the browser as soon as it is executed. So since you copied my code to the top of your script the html output is also at the top.
But why did it echo <div style="background-image: url('bg.jpeg');" ></div> when i wanted it to apply to my page's body?
— Because the echo statements reads "<div style=\"background-image: url('bg.jpeg');\" ></div>"; as its output.
Ok, but how to apply the background-image to body then??
As mentioned earlier code is executed line-by-line, so in order to apply the style to pages's body tag you'll need to call it near your body tag and also modify it to not output the div it currently does.
So assuming your index.php is:
<?php
$my_image = 'bg.jpeg';
echo "<div style='background-image: url($my_image);' ></div>";
?>
<html>
<head><head>
<body>
<nav>Some dummy navigation</nav>
<div>welcome to my website</div>
<footer>Copyright</footer>
</body>
</html>
You'll need to change it to —
<?php
$my_image = 'bg.jpeg';
// don't echo any thing here
?>
<html>
<head><head>
<body style="background-image: url('<?php echo $my_image; ?>')">
<!-- apply the style to body -->
<nav>Some dummy navigation</nav>
<div>welcome to my website</div>
<footer>Copyright</footer>
</body>
</html>
Hopefully i explained it well :)
So I would like to print name of the current page in the title tag of the head.
I include my head in every page like this:
include 'includes/head.php';
This is my head:
<head>
<?php $page = basename(__FILE__, '.php'); ?>
<title><?php echo ucfirst($page); ?><title>
</head>
I thought this would work, but now it just shows "Head" on every page.
I know I can make it work by just putting the $page variable on every page but I would like to prevent this.
So is there any way to print the name of the current page through the included head.php file without adding anything to every page?
Thanks
EDIT
This is how I fixed it:
$page = pathinfo($_SERVER['SCRIPT_NAME'],PATHINFO_FILENAME);
If you were to create a file head.php with the following content
<?php
$xpage = pathinfo( $_SERVER['SCRIPT_NAME'],PATHINFO_BASENAME );
$ypage = pathinfo( $_SERVER['SCRIPT_NAME'],PATHINFO_FILENAME );
echo "
<!--
with extension
{$xpage}
without extension
{$ypage}
-->";
?>
and include in your regular php pages using include '/path/to/head.php' you should get the desired result ~ you will see two options - with or without file extension.
To add this to the document title simply echo whichever option is preferrable
<title><?php echo $ypage;?></title>
Try this enclosing the $page variable in php tags:
<head>
<?php $page = basename(__FILE__, '.php'); ?>
<title><?php echo ucfirst($page); ?><title>
</head>
You have several problems, first one is curly bracket in front of the echo, the second one is that end title tag is missing forward slash and probably last one is that page variable is not inside php tags...
So your code should look like:
<?php $page = basename(__FILE__, '.php'); ?>
<title><?php echo ucfirst($page); ?></title>
You could use a function like this:
head.php
<?php
function head($page) {
echo "<head>";
echo "<title>".ucfirst($page)."<title>";
echo "</head>"
}
index.php
<?php
include 'includes/head.php';
$page = basename(__FILE__, '.php');
head(page);
I'm having trouble getting a PHP script to work. It doesn't seem to be working accurately. I'm trying to make a script to only show HTML or Javascript on the homepage only. This script will be used for multiple things. I did google this, but most answers are for WP. This is vanilla PHP.
Here's what I used:
<!-- Add Only On The Homepage Or Else -->
<?php
$currentpage = $_SERVER['REQUEST_URI'];
if($currentpage=="/" || $currentpage=="/index.php" || $currentpage=="" ) {
echo '
<header id="main-header" class="home">
';
}
else {
echo '
<header id="main-header">
';
}
?>
The results are that it shows the content of else, even though it's the homepage. I tested it on "/" and "/index.php".
I commonly use this snippet:
index.php
if (preg_match('/^m\.[^\/]+(\/(\?.*|index\.html(\?.*)?)?)?$/i', $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'])) {
readfile('index.html');
} else {
// Your framework bootstrapper or your own logic
}
Why does this if statement have each of its conditionals wrapped in PHP tags?
<?php if(!is_null($sel_subject)) { //subject selected? ?>
<h2><?php echo $sel_subject["menu_name"]; ?></h2>
<?php } elseif (!is_null($sel_page)) { //page selected? ?>
<h2><?php echo $sel_page["menu_name"]; ?></h2>
<?php } else { // nothing selected ?>
<h2>Select a subject or a page to edit</h2>
<?php } ?>
Because there is html used. Jumping between PHP and HTML is called escaping.
But I recommend you not to use PHP and HTML like this. May have a look to some template-systems e.g. Smarty or Frameworks with build-in template-systems like e.g. Symfony using twig.
Sometimes its ok if you have a file with much HTML and need to pass a PHP variable.
Sample
<?php $title="sample"; ?>
<html>
<title><?php echo $title; ?></title>
<body>
</body>
</html>
This is not much html but a sample how it could look like.
That sample you provided us should more look like....
<?php
if(!is_null($sel_subject))
{ //subject selected?
$content = $sel_subject["menu_name"];
}
else if (!is_null($sel_page))
{ //page selected?
$content = $sel_page["menu_name"];
}
else
{ // nothing selected
$content = "Select a subject or a page to edit";
}
echo "<h2>{$content}</h2>";
?>
You could echo each line of course. I prefer to store this in a variable so I can easy prevent the output by editing one line in the end and not each line where I have added a echo.
According to some comments i did a approvement to the source :)
Because the <h2> tags are not PHP and will display an error if the PHP Tags are removed.
This code will display one line of text wrapped in <h2> tags.
This is called escaping.
Because you cannot just type html between your php tags.
However, I would rather use the following syntax because it is easier to read. But that depends on the programmers opinion.
<?php
if(!is_null($sel_subject))
{ //subject selected?
echo "<h2>" . $sel_subject["menu_name"] . "</h2>";
}
elseif (!is_null($sel_page))
{ //page selected?
ehco "<h2>" . $sel_page["menu_name"] . "</h2>";
}
else
{ // nothing selected
echo "<h2>Select a subject or a page to edit</h2>";
}
Because inside the if-statement there is an HTML code, which you can put it by closing PHP tags and open it again like this:
<?php if(/*condition*/){ ?> <html></html> <?php } ?>
or:
<?php if(/*condition*/){ echo '<html></html>' ; }
That is because in this snippet we see html and php code. The code <?php changes from html-mode to php-mode and the code ?> changes back to html-mode.
There are several possibilites to rewrite this code to make it more readable. I'd suggest the following:
<?php
//subject selected?
if (!is_null($sel_subject)) {
echo "<h2>" . $sel_subject["menu_name"] . "</h2>";
//page selected?
} elseif (!is_null($sel_page)) {
echo "<h2>" . $sel_page["menu_name"] . "</h2>";
// nothing selected
} else {
echo "<h2>Select a subject or a page to edit</h2>";
}
?>
using the echo-command to output html, you don't need to change from php-mode to html-mode and you can reduce the php-tag down to only one.
I need to include html, not from file, just simple code.
I have main content included by:
<?php
$content = array(
'001'=>'content/001_001.php',
'002'=>'content/001_002.php',
'003'=>'content/001_003.php'
);
if(in_array($_GET['show'], array_keys($content))) {
include($content[$_GET['show']]);
} else {
include('content/001_001.php');
}
?>
And on a side i'd like to include simple html, but that's more like 3 buttons in each category, so cloning lots of *.html & *.php files won't be right and clean work.
In case of opened page: ?show=001, on a side would be added <div>001</div>;
?show=002, on a side would be added <div>002</div> and etc.
If I understand your question correctly, you want to load HTML code from an array rather than from a file. You can do this by changing your include to echo.
<?php
$content = array(
'001'=>'<div>001</div>',
'002'=>'<div>002</div>',
'003'=>'<div>003</div>'
);
if(!empty($_GET['show']) && isset($content[$_GET['show']])) {
echo $content[$_GET['show']];
} else {
echo $content['001'];
}
?>
