First off, I don't know much (quite nothing) about PHP. I'm more familiar with CSS.
I'm making use of Ben Ward script Tumblr2Wordpress (here's the script on GitHub) to export my Tumblr blog in XML (so I can import it in my Wordpress blog). This script reads tumblr's API, queries elements, do a bit of formatting and export the whole thing in HTML.
I need to customize it just a bit to fit my needs. For example in the following function I need the blockquote to become a specific class of blockquote:
function _doBlockQuotes_callback($matches) {
$bq = $matches[1];
# trim one level of quoting - trim whitespace-only lines
$bq = preg_replace('/^[ ]*>[ ]?|^[ ]+$/m', '', $bq);
$bq = $this->runBlockGamut($bq); # recurse
$bq = preg_replace('/^/m', " ", $bq);
# These leading spaces cause problem with <pre> content,
# so we need to fix that:
$bq = preg_replace_callback('{(\s*<pre>.+?</pre>)}sx', array(&$this, '_doBlockQuotes_callback2'), $bq);
return "\n". $this->hashBlock("<blockquote>\n$bq\n</blockquote>")."\n\n";
}
At first, I thought it will be as simple as adding the class I need inside the blockquote HTML tag, like so <blockquote class="big"> But it breaks the code.
Is there a way I could add this HTML attribute as is in the PHP script? Or do I need to define the output of this <blockquote>somewhere else?
Thanks in advance for any tips!
P.
Your guess was correct, but you need to escape the quotes with backslashes:
return "\n". $this->hashBlock("<blockquote class=\"big\">\n$bq\n</blockquote>")."\n\n";
Otherwise, PHP assumes that your string ends at the class=" quote.
You can escape double quotes ".
"<blockquote class=\"big\">"
How ever, if you're going to use single quotes '. It's unnecessary.
'<blockquote class="big">'
You need to escape the quote marks
<blockquote class=\"big\">

I need to do some cleanup on strings that look like this:
$author_name = '<a href="http://en.wikipedia.org/wiki/Robert_Jones_Burdette>Robert Jones Burdette </a>';
Notice the href tag doesn't have closing quotes - I'm using the DOMParser on a large table of these to extract the text, and it borks on this.
I would like to look at the string in $author_name;
IF the first > does NOT have a " before it, replace it with "> to close the tag correctly. If it is okay, just skip and do the next step. Be sure not to replace the second > at all.
Using php regex, I haven't been able to find a working solution - I could chop up the whole thing and check its parts, but that would be slow and I think there must be a regex that can do what I want.
TIA
What you can do is, find the first closing tag, with or without the double-quote ("), and replace it with (">):
$author_name = preg_replace('/(.+?)"?>(.+?)/', '$1">$2', $author_name);
http://www.barattalo.it/html-fixer/
Download that, then include it in your php.
The rest is quite easy:
$dirty_html = ".....bad html here......";
$a = new HtmlFixer();
$clean_html = $a->getFixedHtml($dirty_html);
It's common for people to want to use regular expressions, but you must remember that HTML is not regular.
I have a set of page soure code that has elements such as
<p class='style1'>, <p class=3DMsoNormal>, <span style=3D'font-size:12.0pt'>, <p class=3DMsoNormal>
but i want am trying to replace the all single quotes with double quotes in the all of the source code and those that dont have quotes to receive double quotes such as
<p class=3DMsoNormal and remove the text '3D' from all those that have it.
Below are a series of functions i tried that didn't work. Can someone help me find a solution to this? Thanks
<?php
// test files holds the source code
$html_part = file_get_contents('testRegex.html');
$cSeq = "/(.*)='(.*)'/"; //code sequence
$nSeq = "/(.*)="."(.*)"."/"; //new sequence
preg_match_all($cSeq, $html_part, $matches);
preg_replace($cSeq, $nSeq, $html_part);
echo $html_part;
?>
I'm not sure this regex's are the way to go.
Maybe consider using a parser to read in the file, and write it back out / prettify it.
I've used Beautiful Soup in the past.
preg_replace("/(.*)?='(.*)?'/","\\1=\"\\2\"",$str)
you need to use backreference http://www.regular-expressions.info/brackets.html
You might want to take a look at quoted_printable_decode() instead of removing the '3D' manually.
I have a php var which, when echoed, writes a JS function into the source of a page. The function loops through a CSV and so it has the following line within it:
$str="var lines = data.split('\n');";
At the present time, when echoed, I get this 'correct' JS written into the source:
var lines = data.split('
');
Instead, I want to echo the literal string \n into the source of the page.
Can anyone point me in the right direction? Thanks.
Escape the slash.
"\\n"
So that it is treated as a slash instead of an escape character.
Try this:
$str="var lines = data.split('\\n');";
you can escape \ like this: \\.
But I would put the whole JS functionality into a .js file, include that from the generated HTML, and call the specific function when needed. And generate a minimalistic js code, like var config = {....} if I have to communicate some page related information.
You almost never need dynamically generated JS code. It's a lot harder to read and you're wasting CPU and network bandwidth...
Either the solutions in the earlier answers, or invert the quotes by using single quotes as the PHP string delimiter:
$str='var lines = data.split("\n");';
Or escape the inner quotes, if you want to keep single quotes for javascript as well when using single quotes as the PHP string delimiter.
$str='var lines = data.split(\'\n\');';
See the docs on quoted strings in PHP as well about how single quoted strings and double quoted strings behave differently.
In my PHP code, I'm setting up an area for people to enter their own info to be displayed. The info is stored in an array and I want to make it as flexible as possible.
If I have something like...
$myArray[]['Text'] = 'Don't want this to fail';
or
$myArray[]['Text'] = "This has to be "easy" to do";
How would I go about escaping the apostrophe or quote within the array value?
Thanks
Edit: Since there is only a one to one relationship, I changed my array to this structure...
$linksArray['Link Name'] ='/path/to/link';
$linksArray['Link Name2'] ='/path/to/link2';
$linksArray['Link Name2'] ='/path/to/link3';
The plan is I set up a template with an include file that has these links in a format someone else (a less technical person) can maintain. They will have direct access to the PHP and I'm afraid they may put a single or double quote in the "link name" area and break the system.
Thanks again.
POSSIBLE SOLUTION:
Thanks #Tim Cooper.
Here's a sample that worked for me...
$link = "http://www.google.com";
$text = <<<TEXT
Don't you loving "googling" things
TEXT;
$linksArray[$text] = $link;
Using a heredoc might be a good solution:
$myArray[]['Text'] = <<<TEXT
Place text here without escaping " or '
TEXT;
PHP will process these strings properly upon input.
If you are constructing the strings yourself as you have shown, you can alternate between quotation styles (single and double)...as in:
$myArray[]['Text'] = "Don't want this to fail";
$myArray[]['Text'] = 'This has to be "easy" to do';
Or, if you must escape the characters, you use the \ character before the quotation.
$myArray[]['Text'] = 'Don\'t want this to fail';
$myArray[]['Text'] = "This has to be \"easy\" to do";
If you really want to make i easy, use a separate configuration file in either INI or XML style. INI is usually the easiest for people to edit manually. XML is good if you have a really nested structure.
Unless you are letting users enter direct PHP code (you probably aren't), you don't have to worry about what they enter until you go to display it. When you actually display the info they enter, you will want to sanitize it using something like htmlentities().
Edit: I realize I may be misunderstanding your question. If so, ignore this! :)
You can use the addslashes($str) function to automatically escape quotes.
You can also try htmlentities, which will encode quotes and other special values into HTML entities: http://php.net/manual/en/function.htmlentities.php
when I view source on my php page I get " for a quote. But instead, I would like " to be used in the source code. I have no control over manually replacing it so Im wondering if there is a function to do such a thing.
If you have access to the PHP and want to change all html special characters to their rightful variations use:
print htmlspecialchars_decode($string);
You could do this very simply using str_replace.
$string = str_replace('"', '"', $string);
However, as Levi said, why not just leave it this way? It should have no effect on the display.
