as I cant find exact answer to my question I decided to ask for help posting my question here. So, I have a page content which I get with file_get_contents and want to preg_match this url:
http://sample.com/Last/LastSearch.ashx?q=cnt=1&day=5&keyword=sample&location=15&view=v
from
Last
Please help me.
Why not use the DOM? That's what it's for...
If you insist on a regex, try (in PHP)
if (preg_match('/<a href="javascript:LastURL\(\'([^\'])*\'/', $subject, $regs)) {
$result = $regs[1];
} else {
$result = "";
}
or (in JavaScript)
var myregexp = /<a href="javascript:LastURL\('([^'])*'/;
var match = myregexp.exec(subject);
if (match != null) {
result = match[1];
} else {
result = "";
}
As long as the url is always going to start with http:// then you could use the following expression within your preg_match:
(((f|ht){1}tp://)[-a-zA-Z0-9#:%_\+.~#?&//=]+)

I'm trying to pre replace to get dynamic url,
Code is:
<span>
<img src="/List/Detail/c0954c57-57ca-4f32-841d-de2b61a5087c/5358455" />
</span>
I need to extract: only /List/Detail/c0954c57-57ca-4f32-841d-de2b61a5087c/5358455
Ive tried: \/Listing\/AdDetail\/
Try with this:
preg_match("/<img src=\"(.*)\"/", $input_line, $output_array);
Use this regex to get the link between "yourlink"
(?<=")(.*)(?=")
Note: It works in PHP but not in Javascript. Lookbehind is not supported in Javascript!
Note 2: This answer is only specified for your SHORT information. I would suggest you to update your Question with more Details to get an better Code Sample!
public static Set<String> getImgStr(String htmlStr) {
Set<String> pics = new HashSet<>();
String img = "";
Pattern p_image;
Matcher m_image;
String regEx_img = "<img.*src\\s*=\\s*(.*?)[^>]*?>";
p_image = Pattern.compile
(regEx_img, Pattern.CASE_INSENSITIVE);
m_image = p_image.matcher(htmlStr);

img = m_image.group();
Matcher m = Pattern.compile("src\\s*=\\s*\"?(.*?)(\"|>|\\s+)").matcher(img);
while (m.find()) {

return pics;

I'm using JSN Uniform plugin for Joomla to receive emails, but it's not accepting the .company domain as a valid domain. It accepts the usual domains (com, net, org, info, biz,...), but domains like .company aren't accepted.
Now, I'm really not experienced in PHP, as I'm more into JavaScript, but according to my poor knowledge the solution to my problem could be in the form.php file so here is the part of a code.
PHP:
private function _fieldEmail($post, $fieldIdentifier, $fieldTitle, &$validationForm)
{
$postFieldIdentifier = isset($post[$fieldIdentifier]) ? $post[$fieldIdentifier] : '';
$postFieldIdentifier = (get_magic_quotes_gpc() == true || get_magic_quotes_runtime() == true) ? stripslashes($postFieldIdentifier) : $postFieldIdentifier;
$postEmail = $postFieldIdentifier;
if ($postEmail)
{
$regex = '/^[_a-zA-Z0-9-]+(\.[_a-zA-Z0-9-]+)*#[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)*(\.[a-zA-Z]{2,6})$/';
if (!preg_match($regex, $postEmail))
{
$validationForm[$fieldIdentifier] = JText::sprintf('JSN_UNIFORM_FIELD_EMAIL', $fieldTitle);
}
else
{
return $postFieldIdentifier ? $postFieldIdentifier : "";
}
}
else
{
return $postFieldIdentifier ? $postFieldIdentifier : "";
}
}
Could someone help me please with this?
Thanks.
EDIT: I have tried to change regex value from 2,6 to 2, but still no change.
Please see php fiddler here: http://viper-7.com/CqxAMZ
You should replace the regex like this:
$regex = '/^[_a-zA-Z0-9-]+(\.[_a-zA-Z0-9-]+)*#[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)*(\.[a-zA-Z]{2,})$/';
to accept a domain of any size bigger than one. Now it is restricted to sizes between 2 and 6. More on the subject in http://www.regular-expressions.info/repeat.html
Change {2,6} to {2,7} at the end.
That indicates the last part of the regex should contain between 2 and 7 characters ("company" exceeds the limit of 6).
Replace:
$regex = '/^[_a-zA-Z0-9-]+(\.[_a-zA-Z0-9-]+)*#[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)*(\.[a-zA-Z]{2,6})$/';
if (!preg_match($regex, $postEmail))
{
$validationForm[$fieldIdentifier] = JText::sprintf('JSN_UNIFORM_FIELD_EMAIL', $fieldTitle);
}
with:
if (!filter_var($postEmail, FILTER_VALIDATE_EMAIL)) {
$validationForm[$fieldIdentifier] = JText::sprintf('JSN_UNIFORM_FIELD_EMAIL', $fieldTitle);
}
Email validate is more complicated that a one-line regex.
I am using the following code:
preg_match('/url_encoded_fmt_stream_map=(.*?)&/', $response, $fmt_url)
to grab the url_encoded_fmt_stream_map contents from the following url:
http://www.youtube.com/watch?v=ufDIdRyMklw
but it isn't returning anything.
What am I doing wrong? This used to work.
if (preg_match('/url_encoded_fmt_stream_map=(.*?)\\\\u0026amp;/si', $subject, $regs)) {
$result = $regs[1];
} else {
$result = "";
}
there is no & sign in the same sentince so there \\u0026amp; is a kind of & sign encoded. but your code didnt work because /{REGEX}/s the "s" was missing for the dot equals new line
could it be a delimiter problem?or URL encode? for me url_encoded_fmt_stream_map=(.*?)%26 works
Do I do something wrong?
I need the youtube code, but it doesn't return the real value.
if(preg_match_all("http:\/\/www\.youtube\.com\/v\/(.*)(.*)", $row->n_texto, $matches){
$code = $image_to_thumb .= "http://i1.ytimg.com/vi/".$matches[1][0]."/0.jpg";
}
Edit - ircmaxell Based on the comment, the link structure in the text is:
http:// www.youtube.com/v/plMvAh10HVg%26hl=en%26fs=1%26rel=0
Update
The problem is: my code return a link like this:
http://www.youtube.com/v/plMvAh10HVg%26hl=en%26fs=1%26rel=0
Can I stop it with regexp before appear %26hl=en%26fs=1%26rel=0?
Your regex is not correct. There are more than a few things wrong with it. Now, as far as what you want, try this:
#http://(?:.*)youtube.com/v/([^/\#?]+)#
Now, as for why, let's look at the regex:
http://(?:.*)youtube.com
You're looking for a string that starts with http://, has anything after (www., ww2., or nothing).
/v/
You're looking for /v/ as the start of the URL.
([^/\\#?]+)
You're looking for everything else UP TO another /, a query string (?) or a anchor (#). So that should match the ID you're looking for.
So, it would be
if(preg_match("#http://(?:.*)youtube.com/v/([^/\#?]+)#", $row->n_texto, $matches){
$code = $image_to_thumb .= "http://i1.ytimg.com/vi/".$matches[1]."/0.jpg";
}
If you wanted to find all:
if(preg_match_all("#http://(?:.*)youtube.com/v/([^/\#?]+)#", $row->n_texto, $matches){
foreach ($matches[1] as $match) {
$code = $image_to_thumb .= "http://i1.ytimg.com/vi/".$match."/0.jpg";
}
}
the link provided has a space before the 1st w in www.youtube.com, the code you need is :
if(preg_match_all("%http://www\.youtube\.com/v/([\w]+)%i", $row->n_texto , $matches)){
$code = $image_to_thumb .= "http://i1.ytimg.com/vi/".$matches[1][0]."/0.jpg";
}
also, the url you have is encoded, you may want to use urldecode($row->n_texto) before using it.
^http://\w{0,3}.?youtube+\.\w{2,3}/watch\?v=[\w-]{11}
according to http://www.regexlib.com/REDetails.aspx?regexp_id=2569
for example i've got a string like this:
$html = '
test
test
test
hi
';
and i want to append the absolute url to all hrefs where no abolute domain is given.
$html = '
test
test
test
hi
';
whats the best way to do that? i guess something with RegEx, but my RegEx skills are ** ;)
thanks in advance!
found a good way :
$html = preg_replace("#(<\s*a\s+[^>]*href\s*=\s*[\"'])(?!http)([^\"'>]+)([\"'>]+)#", '$1http://mydomain.com/$2$3', $html);
you can use (?!http|mailto) if you have also mailto links in your $html
$domain = 'http://mydomain';
preg_match_all('/href\="(.*?)"/im', $html, $matches);
foreach($matches[1] as $n=>$link) {
if(substr($link, 0, 4) != 'http')
$html = str_replace($matches[1][$n], $domain . $matches[1][$n], $html);
}
The previous answer will cause problems with your first and fourth example because it fails to include a forward slash to separate the page from the page name. Admittedly this can be fixed by simply appending it to the $domain, but if you do that then href="/something.php" will end up with two.
Just to give an alternative Regex solution you could go with something like this...
$pattern = '#'#(?<=href=")(.+?)(?=")#'';
$output = preg_replace_callback($pattern, 'make_absolute', $input);
function make_absolute($link) {
$domain = 'http://domain.com';
if(strpos($link[1], 'http')!==0) {
if(strpos($link[1], '/')!==0) {
return $domain.'/'.$link[1];
} else {
return $domain.$link[1];
}
}
return $link[1];
}
However it is worth noting that with a link such as href="example.html" the link is relative to the current directory neither method shown so far will work correctly for relative links that aren't in the root directory. In order to provide a solution that is though more information would be required about where the information came from.
