I array text from custom field "black, grey, white" with this code:
<?php global $wp_query; $postid = $wp_query->post->ID; echo get_post_meta($postid, 'colors', true); ?>
I want show me like this:
black</br>
grey</br>
white
It's possible with PHP? Many thanks
Use str_replace():
echo str_replace(",", "<br />", get_post_meta($postid, 'colors', true));
If you want to add <br> after a "," you can do this:
$text = preg_replace("/,/", "<br>", get_post_meta($postid, 'colors', true));
str_replace(", " , ", <br />" , $string) ;
The format is ("from", "to" , "what")

How do i remove underscore from this echo?
if($validation->fails())
{
echo '<div class="error_message">', ($validation->errors()->first('first_name')), '</div>';
}
Thank you.
what madness is this?
if($validation->fails()) {
echo '<div class="error_message">' . str_replace("_"," ",($validation->errors()->first('first_name'))) . '</div>';
}
To replace a string char you have to use str_replace function.
Here is an example:
$var = "Hello_World";
$var = str_replace("_"," ",$var);
echo $var;
Output:
Hello World

I have a variable named $html:
$html = '<li class="col">[gallery_id=234]</li>';
I want to get gallery_id (in this case - 234) into another variable from $html.
Easy. Just use regex with preg_match:
$html = '<li class="col">[gallery_id=234]</li>';
preg_match("/\[gallery_id=([0-9].*)\]/is", $html, $matches);
echo '<pre>';
print_r($matches);
echo '</pre>';
I have that print_r in there for debugging/illustration purposes. It would return the following:
Array
(
[0] => [gallery_id=234]
[1] => 234
)
Then to access the result you want, just do this:
echo $matches[1];
The returned value will be:
234
$html = '<li class="col">[gallery_id=234]</li>';
preg_match('!\d+!', $html, $var);
echo $var[0]; //echoes 234

I need to delete words bettwen slashes
I have this string:
This a test UP/PL/EX/TU 2013
this a test 2 MG/MF/RS/TB 2007
I need this output
This a test 2013
this a test 2 2007
The string is dinamically, always changes.
CAN BE DONE WHIT REGEX ?
I'm sure there's a better expression but given the strings in the question this might be good enough.
$string='This a test UP/PL/EX/TU 2013';
$output=preg_replace("/\s[\w\/]+\s/", " ", $string);
echo $output;
$s1 = 'This a test UP/PL/EX/TU 2013';
$s2 = ' this a test 2 MG/MF/RS/TB 2007';
$regex = '|\s*(?:[[:alnum:]]+/)+[[:alnum:]]+\s*|';
echo "$s1 => '", preg_replace($regex, ' ', $s1), "\n";
echo "$s2 => '", preg_replace($regex, ' ', $s2), "\n";
Output:
This a test UP/PL/EX/TU 2013 => 'This a test 2013
this a test 2 MG/MF/RS/TB 2007 => ' this a test 2 2007
HTH
You can use this:
$result = preg_replace('~\h*+\w*+\/(?>\w+\/?)++\h*+~', ' ', $string);

hello I am creating my own theme on wordpress and i want to split the the_title() function into array all i want is the last item on array will be on <span> and the other one is on <h1>.
i tried this
$str = the_title();
$val = explode(" ", $str); // also tried implode
echo "<pre>";
print_r($val);
echo "</pre>";
but it only return array with no items
hope someone will help me.
this wat i really want to be the output
<h1> This is a <span>Title</spam></h1>
thanks in advance
Dont use the_title() as it automatically display the current title of the page.
Beside this Use $post->post_title;.
Lets suppose a sample sentence This is a Title
<?php
global $post;
$str = $post->post_title;
$exp = explode(" ",$str);
echo "<h1>".$exp[0].$exp[1].$exp[2];
echo "<span>".$exp[3]."</span></h1>";
?>
Output will be:
<h1>This is a<span>title</span></h1>
Please use get_the_title() instead of the_title().
Beside is the link for complete understanding :--
http://codex.wordpress.org/Function_Reference/get_the_title
Use following instead of $str = the_title();
$str = get_the_title();
-or-
$str = the_title('', '', false);

I am designing a small application which shoots out status-like tweets from users at the five latest ones. To keep it a small application, I need for it to accept only so many characters on a line and the drop a line just below it. So for example:
Noah: The best thing about Stackoverflow
is that it is full of amazing programmers.
Something along the lines of something like that above. Can you help me with the code below :
echo "<div style='position:relative;top:-20px;padding-top:10px;padding-left:30px;padding-right:30px;'>";
echo "<p> $first_name: $body. </p>";
if (strlen($body <= 100)) {
echo "\n";
}
echo "</div>";
}
wordwrap will do that for you
string wordwrap ( string $str [, int $width = 75 [, string $break = "\n" [, bool $cut = false ]]] )
Example:
$text = "A very long woooooooooooord.";
$newtext = wordwrap($text, 8, "\n", true);
echo "$newtext\n";
A very
long
wooooooo
ooooord.
