I am trying to create an CMS-system where I can add photos to my website, and for the photo-part, I want to have the ability to enter which programs I had used to create that photo.
I should be possible to add more than one program.
Right now I am saving the programs in the database like this:
In the programs-row:
photoshop illistrator indesign
Then at my website, it could be nice if the icons/logos of the used programs, could show up next to the photo.
So my question is how to do create a new div, what a new class, based on the words from the programs-row?
Fx:
photoshop illustrator indesign
Becomes to:
<div class="photoshop"></div>
<div class="illustrator"></div>
<div class="indesign"></div>
Hope you guys can help me with this problem :)
Thanks ;)
Use the explode function and a foreach loop to perform the string manipulation.
$programs = explode(" ", $data);
foreach($programs as $value) {
//Echo out the html - $value contains the program name
}
I leave it to you to figure out how to format the program name with the HTML that you need.
$fx = "photoshop illistrator indesign";
$words = explode(" ", $fx);
array_walk($words, function(&$n) {
echo '<div class="'.$n.'"></div>';
});

I have a variable $mydata (my code is in php) which includes text and some pictures. Every picture included is in this form :
<img src="mypicture.jpg" alt="lala" title="lala" border="0" />
This variable $mydata which has text and images after is inserted into my database (mysql).
What i want to do is, with some way to add to every and each one of the link images into the a href tag, before the img tag, one more attribute and this is rel="lightbox" so that lightbox effect with be applied in all of my images, such as :
<img src="mypicture.jpg" rel="lightbox" alt="lala" title="lala" border="0" />
How to make this in php, can you help me please ?
I guess may we have to use some kind of regular expression in order to implement that but my knowledge of regular expressions is not so advance.. can you help me please ?
$pat = <<<pattern
~(<a href="[^"]+")(><img src="[^"]+" alt="[^"]+" title="[^"]+" border="[^"]+" /></a>)~
pattern;
$html = preg_replace($pat, "\\1 rel=\"lightbox\"\\2", $html);
If all the pictures in $mydata do not have the "rel" attribute, then solution is simple
$mydata = str_replace('<img ', '<img rel="lightbox"', $mydata);
In other cases, only if ">" character does not appear in attribute values, this code works
function rel_adder( $matches ) {
if ( strpos($matches[0], 'rel=') === false ) {
return $matches[1].'rel="lightbox" '. $matches[2];
} else {
return $matches[0];
}
}
$mydata = preg_replace_callback('#(<img )([^>]+)>#i', "rel_adder", $mydata);

I want to remove a particular match of characters from a string.
For example i have strings;
topics-p10-new-model-cars
topics-p20-new-model-cars
topics-p30-new-model-cars
topics-p40-new-model-cars
Then i need the results as,
topics-new-model-cars
topics-new-model-cars
topics-new-model-cars
topics-new-model-cars
That means i want to remove p10-,p20-,etc..
.Those are the page numbers. It may be any number..
How can i do this..? Thanks in advance
Try this:
$result = preg_replace('/\-p\d+/', '', $string);
Note: I'm assuming that the string format does not change (I mean this [topics-p10-new-model-cars]). If my assumption is right.
Then you can do this
if (textBox1.Text.Contains("-p10-"))
{
//topics-p10-new-model-cars
String[] splited = textBox1.Text.Split(new char[] {'-'});
String rString = String.Format("{0}-{1}-{2}-{3}",
splited[0],splited[2],splited[3],splited[4]);
MessageBox.Show(rString);
}
//OR This method
if (textBox1.Text.Contains("-p10-"))
{
String result = textBox1.Text.Replace("p10-", "");
MessageBox.Show(result);
}
With 'preg-replace'::
For, example:
<?
echo preg_replace('/p[0-9]+\-/', '', 'topics-p10-new-model-cars');
?>

For my Laravel-based site, I need to find # and # within text content and replace it with a URL, such as a URL pointing at a user's Twitter page. How can I:
reliably find these strings within text portions of the HTML
replace found instances with a URL
The code for it is vast. You will have to use ajax here, in the textarea/textbox you will have to use "onkeyup" event, every key pressed have to be compared with "#" or "#" then the next character right after "#" has to be searched in the database.
So lets saw the user has typed "#A" till now and the user aims to type "#Ankur" Then as soon as "A" is typed the ajax script will start searching for users in the database and it is retrieved with the name, url and you just have to echo it on the screen.
THis is what you are looking for.. https://stackoverflow.com/a/4277114/829533
$strTweet = preg_replace('/(^|\s)#(\w*[a-zA-Z_]+\w*)/', '\1#\2', $strTweet);
And https://stackoverflow.com/a/4766219/829533
$input = preg_replace('/(?<=^|\s)#([a-z0-9_]+)/i', '#$1', $input);
Using regex it's rather simple. I would make one function that takes a prefix and replacement, like so.
function tweetReplaceObjects($input, $prefix, $replacement) {
return preg_replace("/$prefix([A-Za-z0-9_-])/", $replacment, $input);
}
An example usage would be something like this.
$text = 'hey look, it\'s #stackoverflow over there';
// expected output:
// hey look, it's stackoverflow over there
echo tweetReplaceObjects($text, '#', '$1');

I have an SMF website and i'm actually trying to get some header information which includes the title of a particular thread, the url but i've been finding it difficult to get the unique link affixed to the url using PHP.
Here's the url: http://example.com/index.php?topic=6449.msg6858
I'm actually looking for a way to extract the number 6449, I've tried to use the php GET function but it doesn't work.
$parts = explode('.', $_GET['topic']);
echo $parts[0];
// PHP 5.4+
echo explode('.', $_GET['topic'])[0];
See it in action
This would work, too
echo (int) $_GET['topic'];
See it in action
You want to use a combination of substr and strpos (to find the first occurence of a period)
$number = substr($_GET['topic'], 0, strpos($_GET['topic'], '.'));
// 6449
$arr = array();
if (preg_match("/([\\d]+)([.]{1}msg[\\d]+)/", $_GET["topic"], $arr) == 1) {
echo $arr[1];
} else {
trigger_error("not found", E_USER_ERROR);
}

this is probably an easy question, but I am not really a coder. I maintain a website for a group I belong to, and there are some php forms. I am trying to enhance a form, and I have added this php code, which works (see below). My question is, how can I put this code into a loop so that it repeats 10 times, for "01", "02", etc., "10" strings (code below is for "01" of the series)? Thanks for any help.
//Clean up the Photo Title & Maker Name to remove non-standard chars and replace spaces with underscores and generate a suggested fliename
$photo_01_clean = str_replace(" ","75357",$photo_01_name);
$photo_01_clean1 = str_replace("#","at",$photo_01_clean);
$photo_01_clean2 = preg_replace('/[^a-z0-9]/i', '', $photo_01_clean1);
$photo_01_clean3 = str_replace("75357","_",$photo_01_clean2);
$photo_01_maker_clean = str_replace(" ","75357",$photo_01_maker_name);
$photo_01_maker_clean1 = str_replace("#","at",$photo_01_maker_clean);

You'd require a for loop control structure. You can find tons of resources that would teach you how to do it. example
Var i;
For (i =1; i<11; i++)
