use function variables like wordpress

[Makeshift]

hey guys, what i mean about the variables is something like:

Code:

test_function(‘title=home&foo=bar&this=that’);

how can I make something like this work on my website?

you need to build a function then pass the data into it

for example:

Code:

function greet($name=NULL) {

return "Hello $name";

}

Then you call the function and pass in the name…

Code:

echo greet("Makeshift");

//Outputs: "Hello Makeshift"

I know that, but how do i get the function to get each variable passed using ampersands and equal signs like that?

I made this little script for it:

Code:

function _li($args){
$args = explode(‘&’, $args);

$args1 = $args[0];
$args1 = explode(‘=’, $args1);
$args1 = array($args1[0] => $args1[1]);
foreach($args1 as $key => $val){
if($key == ‘text’){$text = $val;}
elseif($key == ‘title’){$title = $val;}
elseif($key == ‘href’){$href = $val;}
}

$args2 = $args[1];
$args2 = explode(‘=’, $args2);
$args2 = array($args2[0] => $args2[1]);
foreach($args2 as $key => $val){
if($key == ‘text’){$text = $val;}
elseif($key == ‘title’){$title = $val;}
elseif($key == ‘href’){$href = $val;}
}

$args3 = $args[2];
$args3 = explode(‘=’, $args3);
$args3 = array($args3[0] => $args3[1]);
foreach($args3 as $key => $val){
if($key == ‘text’){$text = $val;}
elseif($key == ‘title’){$title = $val;}
elseif($key == ‘href’){$href = $val;}
}
}

(there’s more to it, but this splits the function variable)

and the usage..

Code:

_li(‘text=Home&title=Go Back Home’);

but this will only take the first 3 variables, of course I can make it as many as I want, but every time i make a new function for something like this, I don’t wanna have to set it for how many variables it’s looking for…

Well – is there any reason why you need to pass them like that firstly? Could you not just create an array and throw that in?

Because I am sure you know this already, that format is how your browser will POST and GET… I am not sure how WP are doing it in their code but I suppose you could explode the data into an array and use it that way…

$var = explode(‘&’, $string);

That would give you an array like

[0]=>title=home
[1]=>foo=bar
[2]=>this=that

Then you are atleast half way there – maybe then you could split them again…

EDIT:

Was just playing around with a double explode idea and thought I would check the PHP.net info on explode – and I found this awesome function

Code:

function doubleExplode ($del1, $del2, $array){

$array1 = explode("$del1", $array);

foreach($array1 as $key=>$value){
$array2 = explode("$del2", $value);
foreach($array2 as $key2=>$value2){
$array3[] = $value2;
}
}

$afinal = array();

for ( $i = 0; $i <= count($array3); $i += 2) {
if($array3[$i]!=""){
$afinal[trim($array3[$i])] = trim($array3[$i+1]);
}
}
return $afinal;
}

So you basically use it like this…

$string = "title=home&foo=bar&this=that";
$myVar = doubleExplode(‘&’, ‘=’, $string);

and you get back a nice array:

Array
(
[title] => home
[foo] => bar
[this] => that
)

Is that more the kind of thing you were looking for?
