I have a lot of these in a file jQuery1332199407617="01" that need removing, however, the bunch of numbers of always different, is that any way I can just deleted everything between jQuery and ="(number is also always different)"?
Thanks in advance.
Sample of part of the file as requested:
(as you can see it adds another jQuery thing each time it is saved.. hence the need to remove it)

This will remove the jQuery text, no matter what numbers are present. It will also take out the excessive space at the end of the tags which is left after the jQuery tags were removed.

//This will erase all the jQuery strings.
$new = preg_replace('/jQuery\d+="\d+"/', '', $old);
//This will take out the extra spaces at the end of the tags that was left open.
$new = preg_replace('/\s+>/', '>', $new);
echo $new;
For more information see: http://php.net/manual/en/function.preg-replace.php
If I understand you correctly, this should work:
$myContent = preg_replace('/jQuery\d+="(\d+)"/g', 'jQuery="${1}"', $myContent);

Hey i want to display some html/css depending on how many rows there are in database basically. Is there a way to do this without echo? Because i'm lost when i have to use many ' '. Here is code sample
<?php foreach ($result as $row) {
}?>
<div id="abox">
<div class="abox-top">
Order x
</div>
<div class="abox-panel">
<p>lorem ipsum</p>
</div>
<br>
<div class="abox-top">
lorem</div>
<div class="abox-panel">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut ac convallis diam, vitae rhoncus enim. Proin eu turpis at ligula posuere condimentum nec eu massa. Donec porta tellus ante, non semper risus sagittis at. Pellentesque sollicitudin sodales fringilla. Ut efficitur urna eget arcu luctus lobortis. Proin ut tellus non lacus dapibus vehicula non sit amet ante. Ut nibh justo, posuere sit amet fringilla eget, aliquam mattis urna.</p>
</div>
There's nothing complicated about it:
Simple/ugly:
<?php while($row = fetch()) { ?>
<div>
<?php echo $row['somefield'] ?>
</div>
<? } ?>
Alternative:
<?php
while ($row = fetch()) {
echo <<<EOL
<div>
{$row['somefield']}
</div>
EOL;
}
and then of course there's any number of templating systems, which claim to separate logic from display, and then litter the display with their OWN logic system anyways.
you can simply use <?= short opening tag introduced in php 5.3 before PHP 5.4.0 came out you had to enable short_open_tag ini but after 5.4.0 tag
here is an example
<?php $var='hello, world'; ?>
<?=$var ?> // outputs world
hope it helps.
Templates engines makes your life a pie
Take Smarty for example, it's pretty good template library. What template engine does is fetch variables to pre defined templates.
Your code in simple php:
<?php
echo 'My name is '. $name. ', that's why I'm awesome <br>';
foreach ($data as $value) {
echo $value['name'].' is awesome to!';
}
?>
Code in smarty:
My name is {$name}, that's why I'm awesome <br>
{foreach $data as $value}
{$value} is awesome to!
{/foreach}
Template engines pros:
Templates are held in separate custom named files. (i.e users.tpl, registration.tpl etc)
Smarty Caches your views (templates).
Simple to use i.e {$views + ($viewsToday/$ratio)}.
A lot of helpers.
You can create custom plugins/functions.
Easy to use and debug.
Most importantly: It separates your php code from html!
Template engines cons:
Sometimes hard to grip the concept of working for beginner.
Don't know any more actually
When I dont want to use a template engine (I like Twig, btw), I do something like this:
1) Write a separate file with the html code and some custom tags where data should be presented:
file "row_template.html":
<div class="abox-top">{{ TOP }}</div>
<div class="abox-panel"><p>{{ PANEL }}</p></div>
2) And then, read that file and do the replacements in the loop:
$row_template = file_get_contents('row_template.html');
foreach ($result as $row) {
$replaces = array(
'{{ TOP }}' => $row['top'],
'{{ PANEL }}' => $row['panel']
);
print str_replace(
array_keys($replaces),
array_values($replaces),
$row_template
);
}
In addition, you can change the content of "row_template.html" without touching the php code.
Clean and nice to the eye!
I have json data that looks like this
{
"project_no":1693,
"project_name":"Theresa Project",
"description":"Nonumy euismod ornatus usu te, quodsi viderer accommodare sea cu, ut alterum officiis nec. At deleniti eloquentiam vis. Explicari definitionem ei sea. No nec erat fugit voluptaria, in his elit discere fastidii. Aperiri virtute no eos. Te per habemus vulputate, partem iuvaret intellegebat eam in.",
"project_cost":10000.00,
}
{
"project_no":1664,
"project_name":"School Supplies for Children",
"description":"Nonumy euismod ornatus usu te, quodsi viderer accommodare sea cu, ut alterum officiis nec. At deleniti eloquentiam vis. Explicari definitionem ei sea. No nec erat fugit voluptaria, in his elit discere fastidii. Aperiri virtute no eos. Te per habemus vulputate, partem iuvaret intellegebat eam in. ",
"project_cost":8000.00,
},
I have over 60 records, With php I want to show 10 records on each page and dynamically populate the page numbers based on how many records I have.
Heres how I'm displaying the data.
$json = file_get_contents('http://linktojsondata.com');
$obj = json_decode($json, true);
<?php
$i = 0;
foreach ($obj as $project_name => $project_info) { ?>
<a href="single-project-detail.php/<?php echo $project_info['project_no'];?>">
<img class="img-thumbnail" alt="" src="<?php echo $project_info['featured_image_url']; ?>">
</a>
<a href="single-project-detail.php/<?php echo $project_info['project_no'];?>">
<?php echo $project_info['project_name']; ?>
</a>
<p>
<?php $string = strip_tags($project_info['description']);?>
</p>
<?php if (++$i == 10) break; } ?>
Here is a start, you will split the json array into blocks of 10 using array_chunk, and then loop through this using the page number $_GET['p'] - 1 so your page url may look like page.php?p=2 which will select the second set of data.
$pages = array_chunk(json_decode($json, true), 10, true);
foreach ($pages[$_GET['p'] - 1] as $project_name => $project_info) {
// your code
}
I've got a weird layout to get around and am at a loss, even in the planning stage. Essentially I need to separate out all content that's not a .gallery and put it into an <aside />. I initially considered a plugin using the edit_post hook from the Plugin API, but have since decided against it because this content change is layout specific and I want to maintain a clean database. So...
How can I parse through WP's the_content for content that's not .gallery? Admittedly not a PHP guy, so I doubly appreciate the help!
As per Michael's comment below - here's an example of WP's the_content class output:
HTML
<div class="entry-content">
<div class="gallery">
<dl class="gallery-item">
<dt class="gallery-icon portrait">
<img src="/imagePath/etc.jpg" class="attachment-thumbnail">
</dt>
</dl>
<dl class="gallery-item">
<dt class="gallery-icon portrait">
<img src="/imagePath/etc.jpg" class="attachment-thumbnail">
</dt>
</dl>
<dl class="gallery-item">
<dt class="gallery-icon portrait">
<img src="/imagePath/etc.jpg" class="attachment-thumbnail">
</dt>
</dl>
</div>
<p>Curabitur vulputate, ligula lacinia scelerisque tempor, lacus lacus ornare ante, ac egestas est urna sit amet arcu. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. Sed molestie augue sit amet.</p>
<ul>
<li>Item A</li>
<li>Item B</li>
<li>Item C</li>
</ul>
</div>
Desired Output
<div class="entry-content">
<div class="gallery">
<dl class="gallery-item">
<dt class="gallery-icon portrait">
<img src="/imagePath/etc.jpg" class="attachment-thumbnail">
</dt>
</dl>
<dl class="gallery-item">
<dt class="gallery-icon portrait">
<img src="/imagePath/etc.jpg" class="attachment-thumbnail">
</dt>
</dl>
<dl class="gallery-item">
<dt class="gallery-icon portrait">
<img src="/imagePath/etc.jpg" class="attachment-thumbnail">
</dt>
</dl>
</div>
<aside>
<p>Curabitur vulputate, ligula lacinia scelerisque tempor, lacus lacus ornare ante, ac egestas est urna sit amet arcu. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. Sed molestie augue sit amet.</p>
<ul>
<li>Item A</li>
<li>Item B</li>
<li>Item C</li>
</ul>
</aside>
</div>
You'll want to use a Dom Parser for this. Here's an example in how you can go about it using your markup as an example. Testing yielded the desired results, so hopefully this will give you the head start you need:
add_filter( 'the_content', 'wrap_nongallery_aside', 20 );
function wrap_nongallery_aside($content){
$dom = new DOMDocument();
$dom->loadHTML($content); // Replace with Edit below if PHP >= 5.4
$aside = $dom->createElement('aside');
$xpath = new DOMXPath($dom);
$not_gallery = $xpath->query('//div[#class="entry-content"]/*[not(contains(#class, "gallery"))]');
foreach($not_gallery as $ng){
$aside->appendChild($ng);
}
$dom->getElementsByTagName('div')->item(0)->appendChild($aside);
return $dom->saveHTML();
}
Edit:
If you're using PHP >= 5.4, then you can easily remove any extra <html> and <body> tags from the generated markup by using the following:
$dom->loadHTML($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);
Maiorano84's answer worked beautifully, but prior to his reply I worked out an alternate method that's less specific to my situation, so I figured it'd be good to share.
I had originally written off the plugin approach because it requires changing post content itself - not just the format of the output, but realized that plugins live independent of the theme installation. Below is a very simple, developer targeted plugin that converts a [aside /] shortcodes into HTML elements. It's entirely based on BSD Aside by Sean D Burkin. I'll eventually include a button for the WP text editor and open source it.
<?php
/*

if ( !is_admin() ){
add_filter('the_content', 'handle_rw_aside');
}

{
return substr(md5(rand()), 0, $length);
}
function generate_place_marker()
{
return '#' . generate_random_str( 10) . '#';
}
function GetBody( $aside_instruction) {
return preg_replace( '~^((<p>)? \S+\s*=\s*.*?(<br \/>|<\/p>)\n?)*~mi', '', $aside_instruction);
}
function handle_rw_aside($the_content)
{
$begin = generate_place_marker();
$end = generate_place_marker();
$new_content = preg_replace(
'~^((<p>)?\[aside\](<br />|</p>))(.*?)(^(<p>)?\[\/aside\](<br />|</p>))~ms',
$begin . '$4' . $end,
$the_content);
$new_content = preg_replace_callback(
'~^(<p>)?(!+\[\/?aside\])~m',
function ($match) {
return $match[1] . substr( $match[2], 1);
},
$new_content);
$pattern = '~'.$begin.'(.*?)'.$end.'~s';
return preg_replace_callback(
$pattern,
function ($match) {
$aside_instruction = $match[1];
$body = GetBody( $aside_instruction);
$aside = '<aside class="contentAside">' . $body . '</aside>';
return $aside;

?>
I am working with html document generated from Micrsoft Word 2007/2010. Besides generating incredibly dirty html, word also has the tendency of using both block and inline style. I am looking for a php library would merge block into already existing inline style element.
Edit
The goal is to construct a html block preserve the original formatting and editable in WYSIWYG editor like tinyMCE
Example
If the original html is:
<html>
<head>
<style>
.normaltext {color:black;font-weight:normal;font-size:10pt}
.important {color:red;font-weight:bold;font-size:11pt}
</style>
<body>
<p class="normaltext" style="font-family:arial">
Lorem ipsum dolor sit amet, consectetur adipiscing elit.
In ut erat id dui mollis faucibus. Mauris eu neque et eros tempus placerat.
<span class="important">Nam in purus nisi</span>, vitae dictum ligula.
Morbi mattis eros eget diam vulputate imperdiet.
<span class="important" style="color:green">Integer</span> a metus eros.
Sed iaculis porta imperdiet.
</p>
</body>
</html>
Should become:
<html>
<head>
<body>
<p style="font-family:arial;color:black;font-weight:normal;font-size:10pt">
Lorem ipsum dolor sit amet, consectetur adipiscing elit.
In ut erat id dui mollis faucibus. Mauris eu neque et eros tempus placerat.
<span style="color:red;font-weight:bold;font-size:11pt">Nam in purus nisi</span>, vitae dictum ligula.
Morbi mattis eros eget diam vulputate imperdiet.
<span style="color:green;font-weight:bold;font-size:11pt">Integer</span> a metus eros.
Sed iaculis porta imperdiet.
</p>
</body>
</html>

Porting code from either of the sources to PHP, or using any of the available APIs should do the trick of getting your CSS styling inline.
See the CssToInlineStyles project which does exactly what you want.
No, but try this instead, copying and pasting from word into http://ckeditor.com/ or tinymce, etc does clean it up A LOT, thought it's still not perfect it will get you much closer.
I finally managed to get it to work. The code is based off of
http://blog.verkoyen.eu/blog/p/detail/convert-css-to-inline-styles-with-php
with once simple change:
Moving the line
// add new properties into the list
foreach($rule['properties'] as $key => $value) $properties[$key] = $value;
up to the begining of the loop, right after where $properties is declared.
To make this work for WordPress however, one additional change is needed. DomDocument replace &nbps; from the document with blanks, which breaks WordPress update statement and lead to cotent being cut off. Please refer to my other question for the solution:
DOMDocument->saveHTML() converting to space
This problem is detailed in https://wordpress.stackexchange.com/questions/48692/post-content-getting-cut-off-on-blank-space-on-wpdb-update. If you know why this is happening for WordPress, please post your answer there as I would very much like to find out why it is happening.
I have a blog entry that will sometimes contain a lot of text/images, and I want to cut an excerpt from that blog. To be more specific I want to match everything until after the second image tag
below is some sample text.
I've tried a negative lookaheads like
/[\w\r\n;:',."&\s*<>=-_]+(?!<img)/i
but I can't figure out a way to have the lookahead apply to a '+' modifier. Anyone got any clue, I'd be real grateful.

I've been stuck in a room lately, and though it's hard to stay creative all the time, sometimes you need that extra kick. Well for some us we have to throw pictures of true creative genius at ourselves to stimulate us.
So sit back and soak in some inspiration I've come across the past year.

Couldn't find who did this, but couldn't explain the movie any simpler
<figure>
<img class="aligncenter" src="http://brickhut.files.wordpress.com/2011/05/theempirestrikesback1.jpg" alt="" width="540" height="800" />
<figcaption></figcaption>
</figure>
Obvious a straight forward string cutting is not suitable for your second image:
...
<figure>
<img class="aligncenter" src="http://brickhut.files.wordpress.com/2011/05/theempirestrikesback1.jpg" alt="" width="540" height="800" />
<figcaption></figcaption>
</figure>
Cutting after the image would leave unclosed elements:
...
<figure>
<img class="aligncenter" src="http://brickhut.files.wordpress.com/2011/05/theempirestrikesback1.jpg" alt="" width="540" height="800" />
Which could destroy the rendering of the page inside the browser. And it does not play a role if you use preg_match with a regular expression here or some string functions.
What you need is a DOM parser like DOMDocument that is able to process the HTML:
Given some sample HTML code that is similar to yours in question:
$html = <<<HTML
dolor sit amet, consectetuer adipiscing elit. <img src="http://example.com/img-a.jpg"> Aenean commodo
ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes,
nascetur ridiculus mus.
<figure>
<img src="http://example.com/img-b.jpg">
<figcaption>Figure Caption</figcaption>
</figure>
Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim. Donec pede justo, fringilla vel, aliquet nec, vulputate eget, arcu. In enim justo, rhoncus ut.
HTML;
You can now use the DOMDocument class to load the HTML chunk inside a <body> tag - because it's your whole html body for the manipulation. As you use non-standard HTML tags (<figure> & <figcaption>) you should disable warnings about those when loading the string with libxml_use_internal_errors:
$doc = new DOMDocument();
libxml_use_internal_errors(1);
$doc->loadHTML(sprintf('<body>%s</body>', $html));
This is the basic setup of the DOM parser, your HTML is now inside the parser. Now comes the interesting part. You want to create the excerpt until the second image of the document. That means, everything after that element should be removed. Sounds as easy as like cutting a string which we know does not work, but this time the DOM parser does all the work for us.
You only need to obtain all nodes (<tag>, Text, <!-- comments -->, ...) and delete them. All nodes after the second <img> tag in (following document order). Such things can be expressed with XPath:
/descendant::img[position()=2]/following::node()
PHP's DOM parser comes with XPath, so let's do it:
$xp = new DOMXPath($doc);
$delete = $xp->query('/descendant::img[position()=2]/following::node()');
foreach ($delete as $node)
{
$node->parentNode->removeChild($node);
}
The only thing left is to obtain (exemplary output) the excerpt that is left over. As we know it's all inside the <body> tag:
foreach ($doc->getElementsByTagName('body')->item(0)->childNodes as $child)
{
echo $doc->saveHTML($child);
}
Which will give you the following:
dolor sit amet, consectetuer adipiscing elit. <img src="http://example.com/img-a.jpg"> Aenean commodo
ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes,
nascetur ridiculus mus.
<figure><img src="http://example.com/img-b.jpg"></figure>
As this example shows, the <figure> tag is properly closed now.
A similar scenario is to create an excerpt after a specific text-length or word-count: Wordwrap / Cut Text in HTML string
Well, it's not regex, but it should work:
$post = str_ireplace('<img', '!!!<img', $post);
list($p1, $p2) = explode('!!!', $post);
$keep = $p1 . $p2;
Puts a split marker before the image tags (!!!), splits on them and keeps the first two chunks, which should be everything up to the second image tag. No regex required.
Edit: Because this is for a excerpt, you might want to run strip_tags() on the result. It's possible that if you don't, you'll have some opened HTML tags that never get closed.
If you really want regex based solution then here it is:
// assuming $str is your full HTML text
if ( preg_match_all('~^(.*?<img\s.*?<img\s[^>]*>)~si', $str, $m) )
print_r ( $m[1] );
