How do you validate the numeric values with Hypen's (-) ?
I just want to validate the numeric value with Hypen's and without Hypen's.
Thank you so much !
For example 555 or 5-55
You may use preg_match with the regex pattern ^[0-9-]+$:
$input = "867-5309";
if (preg_match("/^[0-9-]+$/", $input)) {
echo "MATCH"; // prints MATCH
}
I suggest for this purpose from the site:
https://www.phpliveregex.com/
use
For example, I wrote a preg_match in the link:
https://www.phpliveregex.com/p/Ep6
You can see
My suggested code:
$input = "867-5309";
echo preg_match("/^[0-9-]+$/", $input) ? 'MATCH' : 'Not MATCH';

I am trying to change words in string, I know laravel Str::replace() function but it converts if you write exact word. This is what i want to do :
$string = " this is #username and this is #username2"
I want to find usernames which starts with "#" and make them like below, i want to add <strong> html tag them :
$newstring = " this is <strong>#username</strong> and this is <strong>#username2</strong>"
I couldnt find the way to change dynamic value on str replace.
Thanks
Use preg_replace
$string = 'this is #username and this is #username2';
$newString = preg_replace('/(\#\w+)/', '<strong>$1</strong>', $string);

How to add line break in laravel language files?
I have tried to use ,, \n\r,
to break line and add new line but all these not work.
return [
'best_hospitality' => 'Simply <br /> the best hospitality',
];
You can use
'best_hospitality' => "<pre>Simply\r\nthe best hospitality</pre>",
or 'best_hospitality' => sprintf ('<pre>Simply%sthe best hospitality</pre>',PHP_EOL ),
please note the use of double quotes in the first example, it is not working with single quotes if you use the \r\n inside the string, this is why
if you try echo(Lang::get('message.best_hospitality')) you will see the new line:
I am not so sure if you need the pre tag, depends where you need to use the Lang for html or not, eg using (double quotes here):
'best_hospitality' => "Simply\r\nthe best hospitality",
and var_dump(Lang::get('message.best_hospitality')); exit;
has the output
C:\wamp64\www\test\app\Http\Controllers\TestController.php:24:string 'Simply
the best hospitality' (length=39)
Does this cover your case?
You need HTML Entity Names on your lang files.
Try this :
return [
'best_hospitality' => 'Simply <br> the best hospitality',
];
May I suggest creating a custom helper function for this specific case?
Add this into your helpers.php file:
if (! function_exists('trans_multiline')) {
/**
* Retrieve an escaped translated multiline string with <br> instead of newline characters.
*/
function trans_multiline($key, array $replace = [], string $locale = null): string
{
return nl2br(e(__($key, $replace, $locale)));
}
}
Now you will have a function trans_multiline() available for you in any view, which will behave pretty much like the built-in __() helper.
The function will fetch a localized string of text and replace any newline \r\n symbol with <br> tag.
Caveat: For a proper escaping it must be done before nl2br() function, like you see in the code above. So, to prevent any weird errors due to double-escaping, you must use this custom helper without any additional escaping, like so:
{!! trans_multiline('misc.warning', ['name' => 'Joe']) !!}
Escaping will be handled by the e() function (which is what Laravel uses under the hood of {{ }}) inside the helper itself.
And here's how you define a multiline translation string:
'warning' => "There's only 1 apple, :name!\r\nDon't eat it!"
Make sure to use double-quotes, so PHP actually replaces \r\n with a newline character.
Obviously, parameter replacing still works exactly like with the __() helper.
How to count preg_match matches in smarty? Why is the following not working?
{preg_match("/\[PGN.*](.*)\[\/PGN.*\]/", $code, $match)}
{$match|#count}
As far as I understand your needs, the following does work, just make the regex not greedy:
preg_match_all("~\[PGN\d+](.+?)\[/PGN\d+]~", $code, $match)
I am trying to validate a iban no for germany, but I cannot get pregMatch to work with formhandler. I cannot find a mistake and compared it with the formhandler documentation, but nothing helped. Maybe somebody has a hint for me.
This is my code:
debitiban.errorCheck {
1 = pregMatch
1.value = ^DE\d{2}\s?([0-9a-zA-Z]{4}\s?){4}[0-9a-zA-Z]{2}$
}
The value is directly passed on to PHPs preg_match function, so it has to be a valid PCRE regex pattern. You are missing a delimiter charater in your expression. Try to surround the expression by slashes:
debitiban.errorCheck {
1 = pregMatch
1.value = /^DE\d{2}\s?([0-9a-zA-Z]{4}\s?){4}[0-9a-zA-Z]{2}$/
}
I'm writing my own component for Joomla 1.5. I'm trying to figure out how to generate an "alias" (friendly URL slug) for the content I add. In other words, if the title is "The article title", Joomla would use the-article-title by default (you can edit it if you like).
Is there a built-in Joomla function that will do this for me?
Line 123 of libraries/joomla/database/table/content.php implements JFilterOutput::stringURLSafe(). Pass in the string you want to make "alias friendly" and it will return what you need.
If you are trying to generate an alias for your created component it is very simple. Suppose you have click on save or apply button in your created component or suppose you want to make alias through your tile, then use this function:
$ailias=JFilterOutput::stringURLSafe($_POST['title']);
Now you can insert it into database.
It's simple PHP.
Here is the function from Joomla 1.5 source:
Notice, I have commented the two lines out. You can call the function like
$new_alias = stringURLSafe($your_title);
function stringURLSafe($string)
{
//remove any '-' from the string they will be used as concatonater
$str = str_replace('-', ' ', $string);
$str = str_replace('_', ' ', $string);
//$lang =& JFactory::getLanguage();
//$str = $lang->transliterate($str);
// remove any duplicate whitespace, and ensure all characters are alphanumeric
$str = preg_replace(array('/\s+/','/[^A-Za-z0-9\-]/'), array('-',''), $str);
// lowercase and trim
$str = trim(strtolower($str));
return $str;
}
