I am trying to pull content from one page into another. I could be going about this the wrong way, but I am just trying to get the general method of how it is done. This is what I have so far trying to get the data I need. I am not getting the permalink or the image. The other issue is when applying the substr method to the $content variable it actually cuts the html tags off to making it to where anything after it gets nested into whatever html happens to be in the content. I appreciate any tips you may have. Here is the function I created to try and pull the content in it's initial stage.
function show_post($path) {
$post = get_page_by_path($path);
$title = apply_filters('the_title', $post->post_title);
$image = apply_filters('featured_image', $post->the_post_thumbnail);
$content = apply_filters('the_content', $post->post_content);
$link = apply_filters('the_permalink', $post->get_permalink);
echo '<h3>'.$title.'</h3>';
echo substr($content, 0, 300) . '...';
}
$path is the relative url of the website to where I am pulling content so lets say my url i want to grab data is www.test.com/about/bio I would make the path be about/bio.
I appreciate your help in this.

I am attempting unsuccessfully to nest the use of file_get_html($url) from the simple-html-dom script.
Essentially I am requesting a page that has articles on, these articles are being looped through successfully, I can display the contents of these articles fine, however the image is only visible on the individual article page (once clicked through to that specific article).
Is this possible, why is this methodology not working? Maybe need to specify NEW file_get_html():
<?php
$simplehtmldom = get_template_directory() . "/simplehtmldom/simple_html_dom.php";
include_once($simplehtmldom);
// INIT FILE_GET_HTML
$articleshtml = file_get_html($articles_url);
$articlesdata = "";
// FIND ARTICLES
foreach($articleshtml->find('.articles') as $articlesdata) :
$articlecount = 1;
// FIND INDIVIDUAL ARTICLE
foreach($articlesdata->find('.article') as $article) :
// FIND LINK TO PAGE WITH IMAGE FOR ARTICLE
foreach($article->find('a') as $articleimagelink) :
// LINK TO HREF
$articleimage_url = $articleimagelink->href;
// NESTED FILE_GET_HTML TO GO TOWARDS IMAGE PAGE
$articleimagehtml = file_get_html($articleimage_url);
$articleimagedata = "";
foreach($articleimagehtml->find('.media img') as $articleimagedata) :
// MAKE USE OF IMAGE I WORKED EXTRA HARD TO FIND
endforeach;
endforeach;
endforeach;
endforeach; ?>
My question is regarding the possibility of making nested requests of the file_get_html() script so I can search for the image for a specific article on a separate page, then return to the previous file_get_html loop and move on to the next article?
I believe if it was at all possible would need me to set up something like:
something = new simplehtmldom;
or
something = new file_get_html(url);
What can I try next?
$large_image = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full');
$output .= '<a class="overlay" rel="shadowbox" href="'.$large_image[0].'">';
It's OK, working fine.
But I want, show post's body in popup. I tried like this but not working.
$content = wp_get_attachment_image_src( body($post->ID));
Whats the problem? How can I fix it?
Thanks.
I don't know, maybe because body isn't a function in WP or php, or because you're trying to use a function that return image source (come on the function name tell you by itself what it does) and hope it'll return (by magic) post content?
Here is how you get the content from a post, within the loop:
$content = get_the_content();
And if you're outside the loop, you can do:
$content = $post->post_content;
you can consider alligator popup
check how it works, you will get some idea.
I wanted to remove the images from a WordPress post to give me more control of how I could layout the design for the front page of a website. After doing some messing around and failing, I finally found a great post which had an amazing little piece of code that solved my problem.
<?php
$content = get_the_content();
$postOutput = preg_replace('/<img[^>]+./','', $post->post_content);
echo $postOutput;
?>
But some time i have link above images like:
<img src="PATH_IMAGES">
So, How can remove it?
Change above code by following code which remove link if exist into your content.
$content = get_the_content();
$postOutput = preg_replace('/<img[^>]+./','', $post->post_content);
$postContent = preg_replace("/<a[^>]+\>/i", "", $postOutput);
echo $postContent;
I have tried to use AJAX, but nothing I come up with seems to work correctly. I am creating a menu editor. I echo part of a file using php and manipulate it using javascript/jquery/ajax (I found the code for that here: http://www.prodevtips.com/2010/03/07/jquery-drag-and-drop-to-sort-tree/). Now I need to get the edited contents of the div (which has an unordered list in it) I am echoing and save it to a variable so I can write it to the file again. I couldn't get that resource's code to work so I'm trying to come up with another solution.
If there is a code I can put into the $("#save").click(function(){ }); part of the javascript file, that would work, but the .post doesn't seem to want to work for me. If there is a way to initiate a php preg_match in an onclick, that would be the easiest.
Any help would be greatly appreciated.
The code to get the file contents.
<button id="save">Save</button>
<div id="printOut"></div>
<?php
$header = file_get_contents('../../../yardworks/content_pages/header.html');
preg_match('/<div id="nav">(.*?)<\/div>/si', $header, $list);
$tree = $list[0];
echo $tree;
?>
The code to process the new div and send to php file.
$("#save").click(function(){
$.post('edit-menu-process.php',
{tree: $('#nav').html()},
function(data){$("#printOut").html(data);}
);
});
Everything is working EXCEPT something about my encoding of the passed data is making it not read as html and just plaintext. How do I turn this back into html?
EDIT: I was able to get this to work correctly. I'll make an attempt to switch this over to DOMDocument.
$path = '../../../yardworks/content_pages/header.html';
$menu = htmlentities(stripslashes(utf8_encode($_POST['tree'])), ENT_QUOTES);
$menu = str_replace("<", "<", $menu);
$menu = str_replace(">", ">", $menu);
$divmenu = '<div id="nav">'.$menu.'</div>';
/* Search for div contents in $menu and save to variable */
preg_match('/<div id="nav">(.*?)<\/div>/si', $divmenu, $newmenu);
$savemenu = $newmenu[0];
/* Get file contents */
$header = file_get_contents($path);
/* Find placeholder div in user content and insert slider contents */
$final = preg_replace('/<div id="nav">(.*?)<\/div>/si', $savemenu, $header);
/* Save content to original file */
file_put_contents($path, $final);
?>
Menu has been saved.
To post the contents of a div with ajax:
$.post('/path/to/php', {
my_html: $('#my_div').html()
}, function(data) {
console.log(data);
});
If that's not what you need, then please post some code with your question. It is very vague.
Also, you mention preg_match and html in the same question. I see where this is going and I don't like it. You can't parse [X]HTML with regex. Use a parser instead. Like this: http://php.net/manual/en/class.domdocument.php
I am using php, I want to get the content from url in faster way.
Here is a code which I use.
Code:(1)
<?php
$content = file_get_contents('http://www.filehippo.com');
echo $content;
?>
Here is many other method to read files like fopen(), readfile() etc. But I think file_get_contents() is faster than these method.
In my above code when you execute it you see that it give every thing from this website even images and ads. I want to get only plan html text no css-style, images and ads. How can I get this.
See this to understand.
CODE:(2)
<?php
$content = file_get_contents('http://www.filehippo.com');
// do something to remove css-style, images and ads.
// return the plain html text in $mod_content.
echo $mod_content;
?>
If I do that like above then I am going in wrong way, because I already get the full content in variable $content and then modify it.
Can here is any function method or anything else which get the directly plain html text from url.
Below code is written only to understanding, this is not the original php code.
IDEAL CODE:(3);
<?php
$plain_content = get_plain_html('http://www.filehippo.com');
echo $plain_content; // no css-style, images and ads.
?>
If I can get this function it will be much faster than others. Can it is possible.
Thanks.
Try this.
$content = file_get_contents('http://www.filehippo.com');
$this->html = $content;
$this->process();
function process(){
// header
$this->_replace('/.*<head>/ism', "<?xml version='1.0' encoding='UTF-8'?><!DOCTYPE html PUBLIC '-//WAPFORUM//DTD XHTML Mobile 1.0//EN' 'http://www.wapforum.org/DTD/xhtml-mobile10.dtd'><html xmlns='http://www.w3.org/1999/xhtml'><head>");
// title
$this->_replace('/<head>.*?(<title>.*<\/title>).*?<\/head>/ism', '<head>$1</head>');
// strip out divs with little content
$this->_stripContentlessDivs();
// divs/p
$this->_replace('/<div[^>]*>/ism', '') ;
$this->_replace('/<\/div>/ism','<br/><br/>');

$this->_replace('/\srel=(\'?\"?).*?\\1/ism','');
$this->_replace('/\sid=(\'?\"?).*?\\1/ism','');
$this->_replace('/\sclass=(\'?\"?).*?\\1/ism','');
// remove coments

$this->_replace('/<script[^>]*>.*?\/script>/ism','');
$this->_replace('/<style[^>]*>.*?\/style>/ism','');
// multiple \n
$this->_replace('/\n{2,}/ism','');
// remove multiple <br/>
$this->_replace('/(<br\s?\/?>){2}/ism','<br/>');
$this->_replace('/(<br\s?\/?>\s*){3,}/ism','<br/><br/>');
//tables
$this->_replace('/<table[^>]*>/ism', '');
$this->_replace('/<\/table>/ism', '<br/>');
$this->_replace('/<(tr|td|th)[^>]*>/ism', '');
$this->_replace('/<\/(tr|td|th)[^>]*>/ism', '<br/>');
// wrap and close
}
private function _replace($pattern, $replacement, $limit=-1){
$this->html = preg_replace($pattern, $replacement, $this->html, $limit);
}

you can use regular expression to delete css-script's tags and image's tags, just replace those codes with blank space
preg_replace($pattern, $replacement, $string);
