PHP - Make An Array Global Available

Hey all,

I'm well aware of associative arrays (key/value pairs) and how you can index them in an array like this:

$character = array (name=>"John",
                    occupation=>"Programmer",
                    age=>22,
                    "Learned language "=>"PHP"
);

Then it makes sense to iterate through the key/value pairs of the array using foreach:

foreach ( $character as $key=>$val ){
    print "$key = $val<br>";
}

However, I was watching a video tutorial where he created a $_SESSION array and then created an array associative array: 

$_SESSION['cart'] = array();
[/PHP]
Then he added a function add_to_cart:

function add_to_cart($id){
if(isset($_SESSION['cart'][$id])){
$_SESSION['cart'][$id]++;
return true;
}
else {
$_SESSION['cart'][$id] = 1;
return true;
}
return false;
}

Now that $id variable holds an id converted to integer from the dataabse. So if first item is clicked, id holds a value of integer 1.
When I see this:

$_SESSION['cart'][$id]

I see an array that holds two indexes, each index containing an associative array: [[array() => ''], [1 => '']].
So at index 0 of $_SESSION is [array() => ''].
But then he uses the foreach iterator like this:

function total_items($cart){
$items = 0;
if(is_array($cart)){
foreach($cart as $id => $qty){
$items += $qty; d
}
}
return $items;
}

Now I'm very confused. As you can see in that foreach method, it says that $id (and its corresponding value) is an associative array of $cart array, not $_SESSION array. I don't see how that happened. I thought $cart and id$ were distinct indexes of $_SESSION. I don't see how $id is a key of the $cart array.

Thanks for any explanation to clear my confusion.

Given array
Code: [Select]
Array
(
    [Post] => Array
        (
            [title] => new with has many through for tags
            [body] => hello tags
            [category_id] => 11
            [tags] => one two three
            [mark] => 1
        )

)

I need to make an array something like this:
Code: [Select]
Array
(
[Post] => Array
        (
            [title] => new with has many through for tags
            [body] => hello tags
            [category_id] => 11       
            [mark] => 1
        )
[Tag] => Array
        (
        [0] => Array( [name] => one )
        [1] => Array( [name] => two )
        [2] => Array( [name] => three )
        )
)

How can i make it?

$looponce = 1;
foreach ($this->info as $k => $v) {
if ( (($k == 'subject') && ($v['required'])) && (!$this->settings['customSubject'])) {
for ($i = 0; $i <= 0; $i++) {
$output[] = $this->display_errors('error_system_subject');
}
}
if ( (($k == 'name') && (!$v['required'])) || ((!array_key_exists("name", $this->info)) && ($looponce == 1)) ) {
$output[] = $this->display_errors('error_system_name');
$looponce++;
}
}

That is my loop that i check things in. What i'm more interested in is the name if statement.

If currently checks for a name key in an array(below) and makes sure that it is set to required. If it's not set to required, print out a system error and die()'s.

I'm looking for ways to remove the need for program errors and just change them to what is needed to run.

What i know how to do is, get into the inner array, what i don't know is how to edit the data and put it back exactly as it was given to me. The inner array data can be put back in any order, but the outer array must be in exact order as it was given.


above code $this->info = $formdata;

$formdata = array(
'name' => array('name'=>"Full Name", 'required'=>false, 'type'=>'text'), # This needs to be required=>true, but i can't trust the user, which is why i have the error.
'telephone' => array('name'=>"Telephone", 'required'=>false, 'type'=>'phone'),
);


Any help is greatly appreciated, also am i doing the foreach loop in the code above in an efficient manner or is there another way?

This is the cart array:
$cart = array( "1" => "2", "3" => "4", "5" => "6");
var_dump($cart);
array(3) { [1]=> string(1) "2" [3]=> string(1) "4" [5]=> string(1) "6" }
This is the cart items array:
$cart_items = array();
$cart_items["id"] = $id;
$cart_items["quantity"] = $quantity;
var_dump($cart_items);
array(2) { ["id"]=> array(2) { [0]=> string(1) "1" [1]=> string(1) "1" } ["quantity"]=> array(2) { [0]=> string(1) "1" [1]=> string(1) "1" } }

I want the key to be "id" and the value to be "quantity" like it is for the cart array. How do I define my cart_items array using variables?

Ok, so this seems kinda vague, cus normally thats what you do, however I am talking about a differnt kinds of output from a query... Here is what i am a talking about:

My Query Code:

$query = "SELECT * FROM settings WHERE storeid='store350' "; $which = $handle_db2;
$result = mysql_query($query,$which);
$num = mysql_num_rows ($result);


$id = mysql_result($result,$i,"id");
$storeid = mysql_result($result,$i,"storeid");
$tinypass = mysql_result($result,$i,"tinypass");
$taxsetting = mysql_result($result,$i,"taxsetting");
$gst = mysql_result($result,$i,"gst");
$pst = mysql_result($result,$i,"pst");
$hst = mysql_result($result,$i,"hst");
$canpar = mysql_result($result,$i,"canpar");
$cp_fuelcharge = mysql_result($result,$i,"cp_fuelcharge");
$cp_markup = mysql_result($result,$i,"cp_markup");
$fedex = mysql_result($result,$i,"fedex");
$fe_fuelcharge = mysql_result($result,$i,"fe_fuelcharge");
$fe_markup = mysql_result($result,$i,"fe_markup");
$dhl = mysql_result($result,$i,"dhl");
$dh_fuelcharge = mysql_result($result,$i,"dh_fuelcharge");
$dh_markup = mysql_result($result,$i,"dh_markup");
$tnt = mysql_result($result,$i,"tnt");
$tn_fuelcharge = mysql_result($result,$i,"tn_fuelcharge");
$tn_markup = mysql_result($result,$i,"tn_markup");


As you can see, my variables are the same as my table column names... now if this "project" goes thorugh I could have hundreds of columns, I would hate to have to define each one making my file even larger.

Is there a way to make it dynamically create the variables via an array or something

Theoriticaly something like this:

$query = "SELECT * FROM settings WHERE storeid='store350' "; $which = $handle_db2;
$result = mysql_query($query,$which);
$num = mysql_num_rows ($result);

(While loop here)
$Table_name_var = mysql_result($result,$i,"table_name");
(end while loop)


Possible?

Hello, everyone:

I'm using PHP and Mysql. 

I've got a table of that has 30 fields that I need to add together.  I've got to do this for each record, and there are about 10,000 records.

Which would be more efficient? 

SELECT SUM( field1 + field2...)
or
to make an array for the fields and then use array_sum()

Thanks.

If I have a db with these fields: displayname, title

and I run a successful query on the db, will this code:


if (mysql_num_rows($results) == 0) {
         return "!fail";
      } else {
         while ($row = mysql_fetch_assoc($results)) {
             extract($row);
         }
         
         return $row;
      }


 create an associative array of $var = array(array('displayname' => value, 'title' => value), array('displayname' => value, 'title' => value)...)

If not, is there a way to do so, especially when I will not know the names or number of fields in a db table?

I have the following code:

Code: [Select]
private function buildJSResponse(){
$data = "";
$i = 0;
$arr = array();
while($this->db->row()){
$arr[] = (int)$this->db->field("average");
}
$this->max = max($arr);
$this->min = min($arr);
$this->mid = round(($this->max + $this->min) / 2);
foreach($arr as $val){
$nTime = ($val / $this->max) * 100;
$data .= "data[$i] = ".$nTime.";";
$i++;
}
return $data;
}
It takes an array, finds the max/min and number halfway between the min/max.
The next part I am not sure what to do.

I am making a line graph using the canvas, so I am building a javascript array, which will contain the point on the chart. The problem I am having, is location.
Lets say $max = 110, and $min = 95.
the y position on the graph should be 0 for $max, and 100 for $min, then all the other points need to fall into their place as well.

$nTime is supposed to do that, but it doesn't any suggestions?

The attachment is the result I am getting from my above code.
As you can see the lowest number is 49, so the value with 49 should touch the bottom, which it doesn't.

ok .. so I have this object and I want to make a tab delimited text file from it.

here's what I have so far.


function create_tab_file_from_object($the_object)
{
       $string = '';
       foreach($the_object as $val)
      { 
              $string .= $val.'\t';
      }
       //drop last tab
       $string = substr($string,0,-2);
       filename = 'test_file_pickup.txt';
$fp = fopen('/filepath/'.$filename,'w');
fwrite($fp,$string);
fclose($fp);
}


when i run this i get a text file that looks something like this
field1\tfield2\tfield3\t ... and so on.

How do I get php to make an actual tab delimited file I can open in notepad or excel or whatever..

Thanks in advance,
C

hi friends,

I am using a WordPress theme that uses some of its own functions besides WP functions.

Let me make clear from the start that when I say "Multiple Checkboxes" in the paragraphs below I am NOT talking about checkboxes that each hold a single value.  I am talking about one Checkbox field that allows multiple values to be selected and puts those values into an array with one Name value and stores the output in a string in a single mysql table field.

Right up front, what I need during the Edit Ad functions is the inbuilt function that will Delete the previous Array of values in any multiple checkbox when the ad is updated. Right now updating the ad works for every situation except NO values selected or for Unchecking all previously selected values in a Multiple Checkbox.  If I have, for example, 4 checkboxes selected and unselect all of them before submitting the edited ad it will return the last saved array of values but not an Empty array with no checkboxes selected.

This theme has a Form Builder with a Custom fields builder used by the admin to create forms for a classified ads website. According to which category of ad the Ad creation procedure will show different forms, with different fields.

I had to manually create the capability to generate multiple checkboxes...so that the different multiple checkboxes when selected and updated to the mysql table might hold a variety of values in a comma-delimited array. That works fine.

When the Ad is edited on its own page, (outside of the Wordpress admin dashboard) the problem is that if a user would uncheck all checkboxes in a particular multiple checkbox then the unselected state does not overwrite the previous array of values. What returns after editing is the previous selected values.

I have tried jquery functions but none of them are working the way I had hoped.

so one type of checkbox might have a hypothetical value like this  "name="cp_checkbox_help[]" and if three options are selected then on submit the value could be--- name="cp_checkbox_help[Sunday,Monday,Tuesday]"

I use implode and explode to store the array as comma separated and retrieve the array for editing or display.

I guess I need to create a Null or empty value as a default that only changes when selections are made.

But, since I use implode and explode to make the array "pretty" I don't know if simply specifying nothing will erase a whole array on update.

Here is some of the code used to see how I get what I get--

This displays the checkboxes that I create and name and fill with different values--


case 'checkbox':
 ?>
<?php 
$options = explode(',', $result->field_values);
 echo '<div id="checkboxes"><table width="100%" border="0" cellspacing="0" cellpadding="5">
  <tr>
    <th colspan="2" scope="col">' . $result->field_label. '</th>
  </tr>';
$myvals= explode(',', $post_meta_val);
foreach ($options as $option) {
 {
 ?> 
              
              <tr>
    <td width="4%"><input style="display:inline-block; float:left;" type="<?php echo $result->field_type; ?>" name="<?php echo $result->field_name; ?>[]" class="checkbox<?php if($result->field_req) echo ' required'?>" id="<?php echo $field_label; ?>" value="<?php echo $option; ?>" <?php foreach ($myvals as $myval)
{ if (in_array($myval, array($option), true)) {echo 'checked="yes"';}}?>/></td>
    <td width="96%"style="vertical-align:top; text-indent: 7px; text-align: left;" ><?php echo $option . '</td>
  </tr> ' ?>   



<?php
             }     } echo '  </tr>
</table></div><div class="clr"></div>';
 break; 



Following is the main part of the code that updates the Ad form--



  // update the ad and return the ad id
    $post_id = wp_update_post($update_ad);



    if($post_id) {

        // now update all the custom fields
        foreach($_POST as $meta_key => $meta_value) {
            if (cp_str_starts_with($meta_key, 'cp_'))
if (cp_str_starts_with($meta_key, 'cp_checkbox_charley'))
$meta_value= implode(',', $_POST['cp_checkbox_charley']);
if (cp_str_starts_with($meta_key, 'cp_checkbox_help'))
$meta_value = implode(',', $_POST['cp_checkbox_help']);
if (cp_str_starts_with($meta_key, 'cp_checkbox_hello'))
$meta_value= implode(',', $_POST['cp_checkbox_hello']);
                //echo $meta_key . ' <--metakey <br/>' . $meta_value . ' <--metavalue<br/><br/>'; // for debugging
                update_post_meta($post_id, $meta_key, $meta_value);
        }

        $errmsg = '<div class="box-yellow"><b>' . __('Your ad has been successfully updated.','cp') . '</b> <a href="' . CP_DASHBOARD_URL . '">' . __('Return to my dashboard','cp') . '</a></div>';

    } else {
        // the ad wasn't updated so throw an error
        $errmsg = '<div class="box-red"><b>' . __('There was an error trying to update your ad.','cp') . '</b></div>';

    }

    return $errmsg;

}

Back on the Edit Ad page this is the Submit


                        <p class="submit center">
                            <input type="button" class="btn_orange" onclick="window.location.href='<?php echo CP_DASHBOARD_URL ?>'" value="<?php _e('Cancel', 'cp')?>" />&nbsp;&nbsp;
                            <input type="submit" class="btn_orange" value="<?php _e('Update Ad &raquo;','cp') ?>" name="submit" />

I have a feeling what I need is just a couple of lines to detect no posted values and then... but if one checkbox array has 6 values in it and another checkbox array has only 3 values, for example, do I need to count each specific checkbox for number of values and then overwrite or will one function completely delete the previous array and its commas?

I would really appreciate some expert assistance here!

This question may sound very lame...  ... But I have never able to know how to define a variable that I can use in different functions in a same file. There is no class structure just a PHP file with some functions. Is it possible to use some type of variable that can be share by all functions and that variable should not be a session variable .
Something like:

<?php 
$my_global_var;

function A()
{
// use $my_global_var here
}

function B()
{
// use $my_global_var here and should retain the last value
}
?>

Something like in VB6....

Thanks

Just wanted to know if $_Session was a global thing or does php require cookies setup?   I assumed that I could do something like this:

PAGE: A.php
session_start();
$_Session['Cat'] = 'Meow';

// -----------------------

PAGE: B.php
if (isset($_Session['Cat']) && !empty($_Session['Cat'])){
echo $_Session['Cat'];
}
OUTPUT: Meow

// -----------------------
PAGE: C.php
if (isset($_Session['Cat']) && !empty($_Session['Cat'])){
echo $_Session['Cat'];
}

OUTPUT: Meow

I can't seem to get this to work.   Page: Handler.inc

	// ========================================================= Session Log in / out
	public function logon($username, $password){
		if ($username == "admin" && $password == "coffee"){
			
				session_start();
				$_SESSION['USER_STATUS'] = '1';
				
				echo 'IN SESSION LOGIN HANDLER';
				echo $_SESSION['UserLogged'];
			}
		}
		
	public function logout(){
				$_SESSION['USER_STATUS'] = '0';
				
				echo 'IN SESSION LOGOUT HANDLER';
				
				session_destroy();
				//session_unset();
		}

Page: index.php

if (!isset($_SESSION['USER_STATUS']) && empty($_SESSION['USER_STATUS']) || $_SESSION['USER_STATUS'] == 0){
		if (isset($_POST['username']) && !empty($_POST['username']) && isset($_POST['password']) && !empty($_POST['password'])){
			
			$username = $_POST['username'];
			$password = $_POST['password'];
			
			echo $handler->logon($username, $password); 
		
			}

<LOGIN FORM CODE>

}else{

		if (isset($_SESSION['USER_STATUS']) && !empty($_SESSION['USER_STATUS']) || $_SESSION['USER_STATUS'] == 1){
			echo 'Session name: '. $_SESSION['USER_STATUS'];
		}

	if (isset($_POST['btn_logout']) && !empty($_POST['btn_logout'])){

		$handler->logout();
		echo '<br />Logged out<br />';
		
		}

<LOGOUT FORM BUTTON CODE>

}

Could someone point me in the right direction please. It does not seem to hold its session.        

I have some variables that I have set with the global command but they don't seem to be working correctly. It's probably my order of operation but not sure. Here's the stripped down version of whats going on:



locator()

//functions
function geoip()
global $zip, $city, $areacode, $metrocode, $state, $country, $latitude, $longitude;

function locator()
geoip()
use globals from geoip pass to-
ad_display()

function ad_display()
does some work
stat_tracking()

function stat_tracking()
access global $zip, $city, $areacode, $metrocode, $state, $country, $latitude, $longitude;


The problem is once I call stat_tracking() and try to access the global variables, they are all empty. Just to clarify the chain of events is: page loads, calls locator(), locator() calls function geoip() fine then passes work to ad_display(), ad_display() calls stat_tracking(), stat_tracking() now tries to access the globals I made but all variables are blank if I echo them.

Any ideas?

It's a function=>

Code: [Select]
function _wp_call_all_hook($args) {
global $wp_filter;
//var_dump($wp_filter);
//exit();

reset( $wp_filter['all'] );
do {
foreach( (array) current($wp_filter['all']) as $the_ )
if ( !is_null($the_['function']) )
call_user_func_array($the_['function'], $args);

} while ( next($wp_filter['all']) !== false );
}

Why is $wp_filter variable declared as global ? Was $wp_filter assigned before ?
