Pass A Var From 1 Function To Another

Cant seem to figure this one out for a chained script.

In the code below I need to take the value of $drop_var from function drop_1()
and send it to function drop_2()
So I can add it to the Where clause to limit the results of the third box a little more.

But I cannot get the value to pass to the function.
Any help appreciated.

Hi,

Im trying to pass a variable ($in_this_instance) into, and then back out of a function. The variable goes into the function no problem, and is echo'ed out fine. However the echo after the close of the function, does not give anything out.

Code: [Select]
$in_this_instance = 'boo';

function in_this_instance($data) {
global $in_this_instance;

echo $in_this_instance;

$in_this_instance = 'hoo';

$rep_val = '[front banner]';

$test = strpos($data, $rep_val);
if ($test === false) {
return $data;
} else {
return $data;;
}
}

add_filter('the_content', 'in_this_instance');
echo $in_this_instance;

Could any one give me a pointer please? Many Thanks!

Hi guys,

I have a trouble with my php snippet, when I insert the var function in the url bar something is like:

http://www.mysite.com/delete.php?favorites&id=0

or

http://www.mysite.com/delete.php?whateveritis&id=0

It doesn't get pass the favorites function to delete the id. It is the same things that it goes for each different function.

Here's the current code:

<?php
Code: [Select]
session_start();
define('DB_HOST', 'localhost');
define('DB_USER', 'mydbuser');
define('DB_PASSWORD', 'mydbpass');
define('DB_DATABASE', 'mydbtablename');

$errmsg_arr = array();
$errflag = false;

$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link) {
die('Failed to connect to server: ' . mysql_error());
}

$db = mysql_select_db(DB_DATABASE);
if(!$db) {

die("Unable to select database");
}

function clean($var){

return mysql_real_escape_string(strip_tags($var));
}
$favorites = clean($_GET['favorites']);
$id = clean($_GET['id']);

if($favorites && $id == ''){
// both are empty
$errmsg_arr[] = 'favorites id are missing.';
$errflag = true;
}

if($errflag) {
$_SESSION['ERRMSG_ARR'] = $errmsg_arr;
echo implode('<br />',$errmsg_arr);
}
else {
$insert = array();
if(isset($_GET['id'])) {
$insert[] = 'id = \'' . clean($_GET['id']) .'\'';
}
if(isset($_GET['favorites'])) {
$insert[] = 'favorites = \'' . clean($_GET['favorites']) . '\'';
}

if($favorites && $id) {
mysql_query("DELETE FROM favorites WHERE id='$id'");
$deleted = mysql_affected_rows();
if($deleted > 0)
{
echo "favorites channels is deleted";
}
else
{
echo("favorites is already deleted");
}
}
}
?>
If you do know how to get pass the favorites function, then please say so as i need your help.

Any advice would be much appreicated.

I need someone to explain how to loop through an array ($products) and grab the three values (name, price, & shipping) and have them sent to "all_products" function - see line 13 then 61 thru 64.

I currently have the script partially working by using array_shift which I know is removing the 1st element (name or $product value).
Note: this is the problem (I need $product included in the call to the "all_products" function along with $price & $shipping so that the final output looks as follow:
---------------------------------

Below is a summary of the products you wish to purchase, along with totals:

If it is possible, could somebody give me the exact code (I'm not a programmer) I would need to use?

Thanks for any help on this.

When Passing Parameters, Do I Pass Only What I Need Or Do I Pass Entire Parent Object?

I work with a large codebase and I have this situation come up fairly often: the legacy class has large objects such as:

$design->motor->dimensions->a;
$design->motor->dimensions->bd;
$design->specifications->weight;
$design->data->height;
//etc

When I create a new class, that class sometimes operates on the specific data, so say:

class MyClass
{
    public function compute($weight, $height, $a)
    {
        //stuff
    }
}

//and I call this for example as such:
(new MyClass())->compute($design->specifications->weight, $design->data->height, $design->motor->dimensions->a);

CONS: Potential issue: if design specs change and I need to change things parameters in "compute" function, I need to "re-key" the variables I pass to the function, and adjust things accordinly in MyClass as wel. PROS: only the exact data is being passed, and this data can come from anywhere it is viable, so in effect the function is fairly well separated, I think. Alternative option for me is to pass the entire design object, i.e

class MyClass
{
    public function compute(&$design) //can also be done via DI through a setter or constructor.
    {
         print $design->specifications->weight;
         print ($design->data->height + $design->motor->dimensions->a);
        //stuff
    }
}

(new MyClass())->compute($design);

PROS: In this case when things change internally in which variables are needed and how things are computed, I only need to change the code in compute function of the class itself. CONS: MyClass now needs to be aware of how $design object is constructed. When it comes to this parameter passing, and Dependency Injection like this in general, does Computer Science advocate a preference on this issue? Do I pass the entire object, or do I pass only the bits and pieces I need?

Display One Thing First Loop Pass And Something Else Second Pass

I'm trying to get a simple table to display and am not sure how to make it happen. Table will have just 2 columns. A TIME and an EVENT. What I want to have happen is for the first row to show the TIME and next to that, the EVENT. If a TIME has more than one event going I want the next row to show an empty first cell and then the second event below the first.

If I set up the loop the only way I know how (so far) it would also output the TIME value again and again as many times as there were events for that same time. For example what I don't want is:

9:15 Sunday School
9:15 Nursery Available

What I do want is:

9:15 Sunday School
Nursery Available

Thanks.

If I was pulling back data from MySQL that was like this "monkeys / dogs / cats", how would I grab just "monkeys" from that using PHP?

In other words, I want to grab all text until a "/" is seen.

Preg_replace, Replace Text With A Function

I'm trying to use preg_replace but I can't get it working.

function replaceContent($sContent)
{
$aReplaceTags = array(
"'\[MENU-CARD\](.*?)\[/MENU-CARD\]'is" => '\\1',
"'\[CONTACT-FORM\]'is" => "Contactform",
);

return preg_replace(array_keys($aReplaceTags), array_values($aReplaceTags), $sContent);
}

This works great however when I change '\\1' into a function the output of '\\1' will always be 1.

function replaceContent($sContent)
{
$aReplaceTags = array(
"'\[MENU-CARD\](.*?)\[/MENU-CARD\]'is" => $this->loadMenuCard('\\1'),
"'\[CONTACT-FORM\]'is" => "Contactform",
);

return preg_replace(array_keys($aReplaceTags), array_values($aReplaceTags), $sContent);
}

Anyone knows what I am doing wrong?

Turn Php Function Text Into Links

Say I have a chunk of code that looks like this (contains imagesx):

Code: [Select]
<span style="color: #0000BB">$width </span><span style="color: #007700">= </span><span style="color: #0000BB">imagesx</span><span style="color: #007700">(</span><span style="color: #0000BB">$img</span><span style="color: #007700">);  <br />
within the code I would like to make all the php functions link to php.net

I thought that the following code would work, but it does not, well because there is no spaces around the above word
public function phpLinks($string){
$words = explode(" ", $string);
$str = array();
foreach($words as $word){
if(function_exists($word)){
$str[] = preg_replace("/$word/i", '<a href="//php.net/'.strtolower($word).'">'.$word.'</a>', $word);
}else{
$str[] = $word;
}
}
return implode(" ", $str);
}

I now can not think of a good way to do this, so I am asking does anyone have any suggestions?

Rainbow Text Function: Ignore Html

Hello there,

I am working on a script that will take a user submitted text and display the text in rainbow. I found a very nice function on the Internet and used it as my base. Here is an example of the code.

Code: [Select]
function rainbow($text)
{
/*** initialize the return string ***/
$ret = '';

/*** an array of colors ***/
$colors = array(
'ff00ff',
'ff00cc',
'ff0099',
'ff0066',
'ff0033',
'ff0000',
'ff3300',
'ff6600',
'ff9900',
'ffcc00',
'ffff00',
'ccff00',
'99ff00',
'66ff00',
'33ff00',
'00ff00',
'00ff33',
'00ff66',
'00ff99',
'00ffcc',
'00ffff',
'00ccff',
'0099ff',
'0066ff',
'0033ff',
'0000ff',
'3300ff',
'6600ff',
'9900ff',
'cc00ff');
/*** a counter ***/
$i = 0;

/*** get the length of the text ***/
$textlength = strlen($text);

/*** loop over the text ***/
while($i<=$textlength)
{
/*** loop through the colors ***/
foreach($colors as $value)
{
if ($text[$i] != "")
{
$ret .= '<span style="color:#'.$value.';">'.$text[$i]."</span>";
}
$i++;
}
}
/*** return the highlighted string ***/
return $ret;
}

$post[message] = rainbow($post[message]);

And it works very well

Here is my problem. At times $post[message] will contain some basic html such as a bold tag, user smiley (img tag), a link tag, and so forth. How can I take my function above so that it doesn't edit and add the html font color coding for anything inside html tags where it just skips over them and leaves that part alone? I need this otherwise it will breakup every html tag I might have inside $post[message] and add a font color html tag to it, thus voiding all other html in it.
