PHP - Numerate Array By One Of It's Array's Values

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

Hi all,

I'm a first time poster here and I would really appreciate some guidance with my latest php challenge! I've spent the entire day googling and reading and to be honest I think I'm really over my head and need the assistance of someone experienced to advise the best way to go!

I have a multi dimensional array that looks like (see below); the array is created by CodeIgniter's database library (the rows returned from a select query) but I think this is a generic PHP question as opposed to having anything to do with CI because it related to working with arrays.

I'm wondering how I might go about searching the array below for the key problem_id and a value equal to a variable which I would provide. Then, when it finds an array with a the matching key and variable, it outputs the other values in that part of the array too.

For example, using the sample data below. How would you recommend that I search the array for all the arrays that have the key problem_id and the value 3 and then have it output the value of the key problem_update_date  and the value of the key problem_update_text. Then keep searching to find the next occurrence?

Thanks in advance, as above, I've been searching really hard for the answer and believe i'm over my head!

Output of print_r($updates);

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 

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;

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

I have a Prepared Statement that runs a SELECT statement and returns 2 records, and I would like to store the Field Value for each Record into an Array.

Here is the code I usually use for queries that return just a single value...

// ******************
// Populate Form. *
// ******************

// Build query.
$q2 = "SELECT response
FROM bio_answer
WHERE member_id=?";

// Prepare statement.
$stmt2 = mysqli_prepare($dbc, $q2);

// Bind variable to query.
mysqli_stmt_bind_param($stmt2, 'i', $memberID);

// Execute query.
mysqli_stmt_execute($stmt2);

// Store results.
mysqli_stmt_store_result($stmt2);

// Check # of Records Returned.
if (mysqli_stmt_num_rows($stmt2)>0){
// Details Found.

// Bind result-set to variable.
mysqli_stmt_bind_result($stmt2, $response);

// Fetch record.
mysqli_stmt_fetch($stmt2);

// Close prepared statement.
mysqli_stmt_close($stmt2);

}else{
// Details Not Found.
$_SESSION['resultsCode'] = 'DETAILS_NOT_FOUND_2133';

// Close prepared statement.
mysqli_stmt_close($stmt2);

// Set Error Source.
$_SESSION['errorPage'] = $_SERVER['SCRIPT_NAME'];

// Redirect to Display Outcome.
header("Location: " . BASE_URL . "/members/results.php");

// End script.
exit();
}//End of POPULATE FORM



Can someone help me out with the syntax so that I get an end result like this...

$answerArray[0] = 'I want to be my own boss!!'
$answerArray[1] = 'Don't waste your time trying to do your own Taxes!'


Thanks,

Hi

Just learning PHP and I'm struggling with a very simple problem.

I'm playing around with arrays as i figure they're one of the most important things to know inside out but I can't work out how to change the value of an array element via a loop. I can obviously do it if I just directly write $cars[2] = "test" but not having any luck with the loop.

I've tried using "foreach" and passing a new value to the $value variable but when i do a print_r the values in the array are unchanged.

Code: [Select]



$cars[0]="Saab";
$cars[1]="Volvo";
$cars[2]="BMW";
$cars[3]="Toyota";



foreach ($cars as $key => $value)
  {

$value = "TEST";
echo $key . " " . $value . "<br />";

  }

print_r($cars)

I then tried using a for loop

Code: [Select]
for ($i=0; $i <= count($cars); $i++)

{

echo $cars[$i];

$cars[$i] = "2";


}

But this code just threw up a fatal error as follows:

"Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 16 bytes) in /home/zzzzzzzz/public_html/php_testing/arrays.php on line 27"

So would someone be kind enough to explain where i'm going wrong and why i get the fatal error on the second for loop.

Thanks

I'm doing some work with the Discogs API trying to serialize the data of a release for use in another local application.

A release on Discogs is something like a music album, so it contains the tracklisting, artists, remixers etc.

Here is a sample track row returned from the API (xml)

Code: [Select]
<track>
<artists>
<artist>
<name>Ramirez</name>
<join>And</join>
</artist>
<artist>
<name>Tajada</name>
</artist>
</artists>
<title>Listen To The Drums</title>
<duration>8:10</duration>
</track>
Which more simply looks like this:
Ramirez  And Tajada   -       Listen To The Drums

On this, I need to class the artist "Tajada" as a guest on this track, however, the "role" is defined in the previous artist's XML row:

Code: [Select]
<name>Ramirez</name>
<join>And</join>
How can I sort through the rows to 'swap' these around?

Ideally it would look like this:

Code: [Select]
<track>
<artists>
<artist>
<name>Ramirez</name>
</artist>
<artist>
<name>Tajada</name>
<join>And</join>
</artist>
</artists>
<title>Listen To The Drums</title>
<duration>8:10</duration>
</track>
Thanks for any help.

Hello

I have been taking a look at associative arrays.
I 'sort' of get the key/value idea, but I'm not quite sure if they appropriate for use with 3 items (as opposed to the 2 key/value items.)

In the code below, I can incorporate the 'company' and 'table' values - but I'm not sure how to add the 'id' value (from the query).

I would very much appreciate some guidance here.

Thank you.

Code: [Select]
$a = array(); // 'A' table array
$b = array(); // 'B' table array
$c = array(); // 'C' table array

$query = "SELECT id, company, `table` FROM EXHIBITORS WHERE year = $year ORDER BY company ASC";
$result = mysql_query($query) or die("There was a problem with the SQL query: " . mysql_error());

if (mysql_num_rows($result) > 0) {

while($row = mysql_fetch_array($result)) {

$testCol = substr($row['table'], 0, 1);

if ($testCol == 'A') { $a[$row['company']] = $row['table']; }
else if ($testCol == 'B') { $b[$row['company']] = $row['table']; }
else if ($testCol == 'C') { $c[$row['company']] = $row['table']; }
}

echo "<table>";
foreach($a as $key => $value){ echo "<tr><td>company: $key</td><td>Table: $value </td></tr>"; }
echo "</table>";

echo "<table>";
foreach($b as $key => $value){ echo "<tr><td>company: $key</td><td'>Table: $value </td></tr>"; }
echo "</table>";

echo "<table>";
foreach($c as $key => $value){ echo "<tr>"<td>company: $key</td><td>Table: $value </td></tr>"; }
echo "</table>";

}

else { echo "No Exhibitor data for the year $_POST[selectByYear]"; }

Hello Guys,

I am trying to figure this out..

I have a page that has several check boxes that when checked the values ends up as an array
Like this

1, 3, 9, 6,

That's what it looks like in the database.

I want to compare the values (numbers) submitted with the values in my database table called benefits

Here is the function

I wrote this function and I want to check the values of the submitted values but I am just not sure how to compare the values, especially with a comma in the array.

Code: [Select]

$benefits2 = $_POST['benefits'];

function check_benefits ($benefits2,$member_id,$description,$ip){
$queryb = mysql_query("SELECT * FROM benefits WHERE b_id = $benefits2");
while ($row = mysql_fetch_array($queryb)) {
$benefit_list = $row['b_id'];
}

 if (isset($benefits2)&&( $benefit_list!== $benefits2)) {
 
  Do something here!
 }
 
 }


Thanks for your help!

Hi,

If i had the following array:


$test = array('key1'=>'test1', 'key2'=>'value2', 'key3'=>array('test','test1','test2'));


Is there a way i could change all the values that have the word "test" to "hello"?

So basically end up with the following array:


$test = array('key1'=>'hello1', 'key2'=>'value2', 'key3'=>array('hello','hello1','hello2'));


Is this possible?

Thanks

Hey guys:

If I some multi-dimensional arrays, like so:

Code: [Select]


array {

array {
  [0]=>
     "Path1"
  [1]=>
   "10"
}

}

array {

array {
  [0]=>
     "Path2"
  [1]=>
   "16"
}

array {
  [0]=>
     "Path3"
  [1]=>
   "110"
}

}

How can I add all of the values of key 1? I know its a foreach loop,  but I can't figure it out... would it be this?

Is there any simple way to check if all values in an array are same with an simple if condition

Something like

if( ...some code...) { //yes, all values are same } else { //nope, all are not same }

my PHP Version is 5.2.9-2

Any help would be appreciated.
Basically, i want to check if values in an array are equals to 1.
