PHP - Retrieving Array Values.

I use Popshops Datafeed API and cant figure out an issue im having with an array. I'm trying to retrieve a category name from an array for the current page.

Here is the array code which is in the index.php file.

 $categories = array();
  $categories[] = array( 'name' => 'page name', 
                         'search_options' => array( 'keywords' => 'page keyword' ) );
  $categories[] = array( 'name' => 'page name', 
                         'search_options' => array( 'keywords' => 'page keyword' ) );
  $categories[] = array( 'name' => 'page name', 
                         'search_options' => array( 'keywords' => 'page keyword' ) );


This is how the script calls the current page keyword.
<?php echo ucwords($_REQUEST[$popshops->nameSpace.'keywords']) ?> 

The code above works fine, so I thought all I had to do was change the 'keywords' to 'name' to get what I was looking for. But that does not seem to work?
<?php echo ucwords($_REQUEST[$popshops->nameSpace.'name']) ?> 

I've tried as much as my limited php knowledge can take me, so now I need some advice.

Here is the function in the popshops.php file they use to pull the page name out for the links in the navigation, but I just want to know how to retrieve just the category name for the current page, nothing else.

function customCategoryLink($category) {
    $url = $this->baseURL($this->params);
    
    if (isset($category['search_options']) && sizeOf($category['search_options']) > 0) {
      foreach($category['search_options'] as $key => $value) {
        $url = $this->addParameter($url,$key,$value);
      }      
    } else {
      $url = $this->addParameter($url,'keywords',$category['name']);
    }
    $url = str_replace('?&','?',$url);
    return '<a href="'.$url.'">'.$category['name'].'</a>';
  }

Thanks in advanced!
 

Hello all,

I'm currently working on a project and it is the first time I have had to store/retrieve an array with PHP and MySQL. Basically its a website that has a list of discounts/coupons on it. People can register and submit their discounts and such. I am storing an array for who is eligible for the discount, as well as which categories the discount falls under.

I did some googling and there seems to be tons of thoughts on the best way to do this. Some say to use implode/explode, some say to serialize/unserialize, I was just wondering if there is a common, concrete way to do this?

I will need to be able to search the array for its contents. So if children are eligible for the discount, I need to be able to store that in a database, retrieve it later, and search it for only "Children" so I can display the discounts available only to children.

If someone could please advise the best way to do this and post some examples, it would be greatly appreciated. I learn best with examples that are explained properly.

As part of a form submission, I have several textboxes   The textboxes have an array name such as text[].  I'm sending the textbox values via http request.  Sending an element value via http request is usually be done using document.getElementById, assigning the elements ID to a var and posting the var name .  Then accessing the value using $_POST.  However I'm sending an array of string values.  How do I access the array using $_POST?  Any help appreciated.

Code: [Select]
$a = $landSellCheck[0];
echo("<p>a: $a");
$a = $landSellCheck[1];
echo("<p>a: $a");
$a = $landSellCheck[2];
echo("<p>a: $a");

$i = 0;
$landSellCheck = $landSellCheck[$i];
echo("<p>b: (0): $landSellCheck");
$i = 1;
$landSellCheck = $landSellCheck[$i];
echo("<p>b: (1): $landSellCheck");
$i = 2;
$landSellCheck = $landSellCheck[$i];
echo("<p>b: (2): $landSellCheck");
As can be seen from the output below when I echo my array by manually inserting the index number, it works fine as it should. If I set the index number as a variable and echo it, it works for index value 0, for index value 1 is gives 'a' somehow (no idea where that comes from) and for index value 2 it is empty. What am I doing wrong?

Output is:

a: landSellConfirm7

a: landSellConfirm6

a: landSellConfirm1

b: (0): landSellConfirm7

b: (1): a

b: (2):

Hi, just a very simple question:

I have an array as follows:
$langList = array('English', 'French', 'German', 'Dutch');
What's the easiest way to store this array in an external file, so that multiple php scripts can access its contents? And what is then the php line I need to retrieve the array from the external file?

Thanks!

PLEASE HELP! 
I need help I am a new php user, and am trying to understand how to read a .txt file into an array then to retrieve the index of the array at will.
Code: [Select]
<?php 
//echo $myfile = fopen("ArrayTestFile.txt", "r") . "File exists: " or die("File does not exist or you lack permission to open it! ");
//echo "The contents of the file is " . file_get_contents("ArrayTestFile.txt") . "<br />";
$fh = fopen("ArrayTestFile.txt", 'r+') or die("Failure");
$array = array(); //creation of array
$num = fgets($fh);// recursive call variable $num fgets(.txt line) 
for ($i = 0; $i <= 5; $i++) //for loop loads first 5 of .txt
   {
    $array["i"] = $num; //loads each line of .txt into the array at the loops index.
    echo "Line " . $i . " of the array is " . $array["i"]; // displays the contents of the array in a print message 
   }
?>
Thank you.

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);

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.

Hello all,

I have yet again trouble finding a logical solution to my problem.
I'm fetching an array which can hold 1 or more values.
The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values.

I can't explain it further, so here's the code so far:

Code: (php) [Select]
$files = mysql_fetch_array($get_files);

$a = count($files);

$i = 1;
while ($files) {
$variablename = 'fileName' . $i;
$$variablename = $files['fileName'];
$i++;
}

$output =  array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are?


This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works?

Thank you.

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

Richard

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.

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
