PHP - Generating Array Values For Pie Chart Creations Using Pchart

Hi there,

Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway)

My question is: is there a short-hand way to use a value from an associative array as the key in another associative array?

So for example, given this array:

$the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....);

then this kind of foreach loop doesn't work

Code: [Select]
$new_data = array();
foreach($the_array as $element){
$new_data[$element['name']] = $element['value'];
}

Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it?

Cheers,

PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails.

I have mysql select query shown below retrieving data from a database:

$sql = "
SELECT 
	student, sum( test_score ) as score
FROM 
	test
INNER JOIN 
	level 
ON 
	test.level_id = level.level_id
GROUP BY 
	student"
$result = $mysqli->query($sql, MYSQLI_STORE_RESULT);
if($result)
{
      while ($row = $result->fetch_array(MYSQLI_ASSOC))
       {
	    var_dump($row);
       }
}

On inspection of the retrieved array with var_dump(), i have these result below:

array (size=2)
  'John' => string 'English' (length=2)
  'Score' => string '20' (length=3)

array (size=2)
  'Mary' => string 'Math' (length=3)
  'Score' => string '35' (length=3)

array (size=2)
  'Samuel' => string 'Physics' (length=3)
  'Score' => string '5' (length=3)

 How do I get at and print out the highest score from this set of array values within this context.
 I tried this echo max($row['count']) but i understandably got this feedback:
Warning: max(): When only one parameter is given, it must be an array   Thanks.

I have an array created to control the down states of the my buttons in my navigation. Which is working well. This array will have quite a few strings in it before I'm done.

I then want to conditionally load a CSS file for all the files in that array with the exception of two, is this possible?

In plain in english I want to say If in array apart from these values then load my css file.

My array (will have more values when complete)

Code: [Select]
$otherTitles = array('Product Selector', 'Avon Range', 'Knightsbridge Range', 'Kingston Range' );

My code to load a css file

Code: [Select]
<?php if (in_array($title, $otherTitles)) { ?>
<link rel="stylesheet" type="text/css" href="homepage.css"/>
<?php } ?>

I want all titles in the otherTitles array to get this CSS file apart from two Product Selector and Avon Range.

Thanks

I need to some how pull comma separated images $data[23] from this $data array and then put them into there own array so I can insert them into separate rows in a database.


    
This is the provided array:

$data[0] => VIN
$data[1] => StockNumber
    
...(all the other number here)
    
$data[23] => Image_URLs (comma seperated)
$data[24] => Equipment


// I need something like this (obviously doesn't work?!@#)

$delimiter = ",";
$img = explode($delimiter, $data[23]);

foreach($img as $pic){
$sqlPic = "insert into class_prodimages (pid image rank) values('".$LastId['id']."', '$pic', '".rand(1,20)."')"; 

}

Hello there again!   I have the following construct of array now (schematics):

array[0]
	array[id] = "1"
	array[title] = "title"
array[1]
	array[id] = "3"
	array[title] = "another title"

Now what i want to do, is to assign the parent-array keys to the IDs of it's contents.   This is what it should look like:

array[1]
	array[id] = "1"
	array[title] = "title"
array[3]
	array[id] = "3"
	array[title] = "another title"

How do I do that again? I know I did this some years ago, but I can not remember how.

How do you get the values in an array and name them as variables?

Lets say I want the 0 and the 2...

Array ( => 02.02.2011 [1] => 97% [2] => 538 [3] => 20 [4] => 63,247 (2.20) [5] => 77,639 [6] => 195,617 [7] => 09.13.2010 )

I'm trying to split a url into segments so that a url would be stored in an array. 

Example:
A url like this http://localhost/application/blog/view/Test-Blog-Entry/1

Would look like this in an array:
Code: [Select]
array('blog', 'post', 'Test-Blog-Entry', '1');
It's an MVC url so 'blog' would be controller, 'post', would be method and the last two would be variables.  I want to display the variable values of the array.

Is there an easy way to do this?

I am working in wordpress and things are going good. I made a form, filled it with values and have been able to store those values in a database using a wordpress function. Now my issue is that I want learn how to write them into an array and store them that way. I have been looking at several different ways but can't figure out how to code it. This is my code now

Code: [Select]
function add_slider_box(){
  global $post;
$imageurl = get_post_meta( $post->ID, 'imageurl', true );
$imagelink = get_post_meta( $post->ID, 'imagelink', true );
$imagecap = get_post_meta( $post->ID, 'imagecap', true );

?>
<div style="width: 50%" class="sliderbox">
        <p><label for="imageurl">Image Url: <br />
            <input type="text" class="widefat" id="imageurl" name="imageurl" value="<?php if( $imageurl ) { echo $imageurl; } ?>" /></label></p>
        <p><label for="imagelink">Image Link: <br />
        <input type="text" class="widefat" id="imagelink" name="imagelink" value="<?php if($imagelink) { echo $imagelink; }?>" /></label></p>
        <p><label for="imagecap">Image Caption: <br />
            <input type="text" class="widefat" id="imagecap" name="imagecap" value="<?php if( $imagecap ) { echo $imagecap; } ?>" /></label></p>
           
            <button class="remove_slide button-secondary">Remove This Slide</button>
    </div>
<?php

}

function bigBusiness_save_slider_options($post_id){
global $post;

if( $_POST ) {
update_post_meta( $post->ID, 'imageurl', $_POST['imageurl'] );
update_post_meta( $post->ID, 'imagelink', $_POST['imagelink']);
update_post_meta( $post->ID, 'imagecap', $_POST['imagecap'] );
}

}

so the update_post_meta function is what is saving the information into the database. How do I put that into an array? I was thinking

Code: [Select]
foreach($_POST as $slides)
    $slides[] = array(
               'imageurl' => '$_POST['imageurl'],
               'imagelink' => $_POST['imagelink'],
               'imagecap' => $_POST['imagecap'];
            );

I have been able to use the data out of the database by creating a function
Code: [Select]

function get_half_slider_slides() {
global $post;
$imageurl = get_post_meta( $post->ID, 'imageurl', true );
$imagelink = get_post_meta( $post->ID, 'imagelink', true );
$imagecap = get_post_meta( $post->ID, 'imageurl', true );

return array( $imageurl, $imagelink, $imagecap );
}

and then calling that function in my code like this $slide =  get_half_slider_slides();

I thought since it returned an array that I would be able to do this $slides['imagelink'] $slides['imageurl'] but it doesn't work. What I am trying to do is populate the nivo-slider ( http://nivo.dev7studios.com ) with images from the database. I have been following a tutorial but since the license on the tutorial doesn't cover reusing the code, I am trying to rewrite it in a way that doesn't violate the license agreement. This code is so far is hacked together but completely different from the tut. Can you help?

Thanks

Basically I am pulling data from an XML feed on wowarmory.com
Everything is working as far as getting the item names and even a list of the item levels.
What I am trying to do now is add together all of the item levels in to one value that I will call $calc (I will then divide this by 16 to find the average item level).

I am using a foreach loop to echo the Item Name and it's corresponding item level. I am now trying to grab the item level on each loop so I can add them all up and store them in $calc for further manipulation outside of the loop. I am a complete novice but learning, How would I go about achieving this?

Of course the code I have atm is re-defining $calc every loop, so naturally it isn't working.
Here is my current code:
//Get the UID for each item the character has
    //Then look up the name for that item
    foreach($char_xml->characterInfo->characterTab->items->item as $item)
    {
        //get the item id
        $item_id = $item->attributes()->id;
        //get the xml doc for that item from wow armory
        $url = "http://www.wowarmory.com/item-info.xml?i=" . $item_id;
        $data = fetchXML($url);
        //create a SimpleXML object to parse the xml
        $item_xml = new SimpleXmlElement($data);
        //print the item's name
        echo "<b> Item Name: </b>" . $item_xml->itemInfo->item->attributes()->name . "</br>";
echo "<b><i> iLvL: </i></b>" . $item_xml->itemInfo->item->attributes()->level . "</br>";
//obviously this is wrong, because It is redefining $calc every loop
$calc=$item_xml->itemInfo->item->attributes()->level;
    }
//print the total item level
echo $calc;

as you can see, there are key value pairs like this,
Code: [Select]
[items_name1] => Product Name 1
[items_name2] => Product Name 2
[items_name3] => Product Name 3

those keys aren't constant, I mean, it came from a shopping cart, so the item name depends on how many items were placed in the shopping cart to be purchased.. now my question is,
How to loop to that post array, and get only the item_names plus their corresponding values ?, because I need them and save in a db table 

Hi All, small question here. I was just playing around with a small script I made to obtain an ip-address, remove the dots and than glue the parts together. Not for any use but for practice. But I am having difficulties to accessing the array values. But maybe that because its the first time i am using explode() and print_r. If someone has a spare minute I would be pleased to be enlightened.

<?php
             $ip=$_SERVER['REMOTE_ADDR'];
             echo $ip.'<br />';
             $cleaned_ip = substr($ip,0,6);
             echo $cleaned_ip.'<br />';
             $cleaned_ip2 = print_r(explode('.', $ip, 6)).'<br />';
             // this is the point where I dont know how to get the array values.
             // echo $cleaned_ip2[0].[1].[2];   that doesnt work. ;(
         ?>

Hi again  ,
I am stuck with simplest problem of array .. i searched all forums and couldn't find similar problem..
Iam collecting array post data "data m_name[][email]" from a form, but I don't know how to get 2 array variables at the same time, here's what I tried :

<form action="" method="post" name="myForm">
<div>
      <input type="text" name="m_name[]" />
      <input type="text" name="m_name[][email]" />
</div>

      <input type="text" name="m_name[][email]" />
</div>
        <input type="submit" name="button" id="button" value="Submit" />
</form>

other page where I want to receive above array

<?php
if($_POST)
{

print_r($_POST['m_name']); // Output is : Array ( [0] => someone [1] => Array ( [email] => 3 ) [2] => someone two [3] => Array ( [email] => 4 ) [4] => someone three [5] => Array ( [email] => 5 ) )


while (list ($key,$val) = @each ( $_POST['m_name'])) { 
echo $val.val2 ???"<br/>"; // here I want to get both value $_POST['m_name'] and  $_POST['m_name'] ['email'] since I am putting them in db << 
}
}
?>

I want to get both values of $_POST['m_name'], I don't know how to do it or is there another way to do it?
thankx in advance!! phpfreaks have been very helpful ..

Hi,
I have 2 arrays, named $old_teams1 and $old_teams2.
The arrays have from 6 values upwards. If $old_teams1 looks like this:
Code: [Select]
Array (
[0] => 3
[1] => 4
[2] => 3
[3] => 4

[4] => 1
[5] => 2
)
and $old_teams2 is the has the same mixture of values from 1-4.....
.. How do I create a loop that will change all values of $old_teams1 and $old_teams2 to new values such as, 1->3, 2->4, 3->1, 4->2.... (The new values have been randomly generated).

Hi,

$_POST['arr_name'];


I want to make the search so that am getting the array values and oputting in IN(val1, val2, val3)


Thanks
