PHP - While Loop And Array Problem

i have 2 arrays... first array of lastnames, second array of firstnames

lastAry = array('smith', 'jones', 'reed', 'chan')
firstAry = array('mary', 'chris', 'kim', joe', 'sara', 'tim', 'amy', 'fred')

how do i loop through each lastnames and turn into a string with firstname so it looks like :

smith | mary | chris
jones | kim | joe
reed | sara | tim
chan | amy | fred

I am working with wordpress. I am using a plugin that gets options stored in an array in the database. This is how I get the options

Code: [Select]
$options = get_option('option_tree');
echo $options['exc_cat'];

the exc_cat is a key that stores a set of values. Right now with the code above, it echoes Array. If I do this

Code: [Select]
echo $options['exc_cat'][0];

it returns 5. Which is what I would expect it to do. What I can't figure out is how to get it to store each value which should be a number into 1 variable. What I need to do is loop through each value that is stored in the exc_cat key, return the number seperated by a -1,. So the result should look like this


-1, -5

1 and 5 should be the only two numbers stored in the array at this point. Can you help?

Thanks

Hi

I am trying to tidy up a bit of php code to make the end display much better but I am a bit stuck, I have the following code which takes a mysql query and uses the result to create a google graph.


<?php
$str = "";
  $str .=  "<img src='http://chart.apis.google.com/chart?chs=600x300";
  $str .= "&chd=t:"; 


$i=0;
while($row_Recordset3 = mysql_fetch_assoc($Recordset3)){
 $reading_array[$i] = $row_Recordset3['reading'];
 $date_array[$i] = date("j/n", strtotime($row_Recordset3['date']));
 $i ++;
}
$count=0;
$count = count($reading_array);
if($count>1) {
$rstring = implode(",", (array_reverse($reading_array)));
$dstring = implode("|", (array_reverse($date_array)));
}else{
 echo $count;
}


$str = $str.$rstring;

  $str = $str."&cht=lc&chxl=0:|";
  // We will close the src attribute with \' and to print escape character ' we shall precede it with \

$str = $str.$dstring;

  $str = $str."&chxt=x,y&chds=0,25&chxr=1,0,25,5&chm=o,0044FF,0,-1,8|b,3399CC44,0,1,0&chtt=Electricity Generation for the last 35 days'";
  $str = $str." >";

  //we shall echo the $str that will display the graph
  ?>
  <tr><td>
  <?php
  echo $str;
?>


Currently the result is
http://chart.apis.google.com/chart?chs=600x300&chd=t:10,6,1,11,12,7,6,2,1,1,4,10,1,5,12,3,3,6,1,6,3,3,1,5,3,1,1,6,8,5,8,8&cht=lc&chxl=0:|27/10|28/10|29/10|30/10|31/10|1/11|2/11|3/11|4/11|5/11|6/11|7/11|8/11|9/11|10/11|11/11|12/11|13/11|14/11|15/11|16/11|17/11|18/11|19/11|20/11|21/11|22/11|23/11|24/11|25/11|26/11|27/11&chxt=x,y&chds=0,25&chxr=1,0,25,5&chm=o,0044FF,0,-1,8|b,3399CC44,0,1,0&chtt=Electricity%20Generation%20for%20the%20last%2035%20days

I need to make it display only every 7 dates so that they are readable but I still need the pipes in between to space out the dates correctly so they tie in with the correct point on the graph, like this where I manually removed some dates as a demo
http://chart.apis.google.com/chart?chs=600x300&chd=t:10,6,1,11,12,7,6,2,1,1,4,10,1,5,12,3,3,6,1,6,3,3,1,5,3,1,1,6,8,5,8,8&cht=lc&chxl=0:|27/10|||||1/11|||||6/11|7/11|8/11|9/11|10/11|11/11|12/11|13/11|14/11|15/11|16/11|17/11|18/11|19/11|20/11|21/11|22/11|23/11|24/11|25/11|26/11|27/11&chxt=x,y&chds=0,25&chxr=1,0,25,5&chm=o,0044FF,0,-1,8|b,3399CC44,0,1,0&chtt=Electricity%20Generation%20for%20the%20last%2035%20days

This is beyond my limited stills, can anyone help please?

Thanks

How can I loop an array and process in  groups 100 at a time?

i have an array in the loop but it isn't building up with results.  i want it to check if the array exists, if not then create the array. Then in next loop it pushes a new value into the array.  Below isn't working?...

Code: [Select]

while($row=mysql_fetch_assoc($get));
{
$key = $row['keyword'];

$scope= $_SESSION['scope'];


if (!is_array($scope)) {

$scopenew = array($key);
$_SESSION['scope'] = $scopenew;

                } else {

$scopenew = array_push($scope, $key);
$_SESSION['scope'] = $scopenew;

}


}

I have following in a csv file:

sku,quantity,price
----------------------
ML2225-1/4,10,38.77
ML2225-1/4,20,36
ML2225-1/4,30,33.23
ML2225-5/16,10,35.94
ML2225-5/16,20,33.37
ML2225-5/16,30,30.8
ML2225-3/8,10,34.37
ML2225-3/8,20,31.92
ML2225-3/8,30,29.46
ML2225-7/16,10,34.37
ML2225-7/16,20,31.92
ML2225-7/16,30,29.46
ML2225-1/2,10,34.37
ML2225-1/2,20,31.92
ML2225-1/2,30,29.46
...

I am able to read the file (fgetcsv).  How do I build an array for each unique sku set, then do something, then continue to the next unique sku set?

Thanks,
Mike

Hello everyone! I am new here and this is my first post. I have been a member at another forum which they tend to make fun of newbies instead of helping them learn. That is why I am here 

Below is my script that allows me to upload 6 images at once and this works nicely. However, I am trying to change the variable $newname to increment in each pass so that I can build some if statements for my sql query. I would like the variable to start from $newname1 and should end up with 6 of them with the last being $newname6. That way I can have 6 unique picture variables that I can either update or insert into my table. Any help here would be great!


Code: [Select]
$upload_image_limit = 6; // How many images you want to upload at once?
define('MAX_SIZE', '100');
define('UPLOAD_DIRECTORY', '../memberYard');

// Define a list of extensions we want to allow.
$allowable = array('.gif', '.jpg', '.jpeg', '.png');

$errors = array();
if (isset($_POST['Submit']))
{
    if (!empty($_FILES))
    {
        foreach ($_FILES as $file)
        {
            // No need for a separate function to get a file's extension
            $extension = substr($file['name'], strpos($file['name'], "."));
            $size      = filesize($file['tmp_name']);

            // Check if the file's extension is in the permissable list
            if (!in_array(strtolower($extension), $allowable))
            {
                $errors[] = "File {$file['name']} is of an unknown type.";
                continue;
            }

            // Check that the file size is OK
            if ($size > MAX_SIZE * 1024)
            {
                $errors[] = "File {$file['name']} is too big.";
                continue;
            }

            // Generate a random name for the file and move it
            $newname = substr(md5(microtime()), 0, 12) . $extension;
            $copied = move_uploaded_file($file['tmp_name'], UPLOAD_DIRECTORY . DIRECTORY_SEPARATOR . $newname);

            if ($copied === FALSE)
            {
                $errors[] = "File {$file['name']} could not be uploaded.";
            }
        }
    }
}

Ok so I'll try to explain what I'm trying to do the best I can. I want to build an array that allows me to add/remove/modify the variables used at any point in time without having to rebuild or rewrite a ton of new code.

For example, below is an example list of variables I'd like to use in the array, followed by the code I would like to be automatically repeated.

Example Variables: $materialName1, $materialName2, $materialName3, $materialName4, $materialName5, $materialName6 etc etc etc
Example Code to repeat:
Code: [Select]
echo "<tr><td>Material: $materialName1</td><td>Rate: $materialName1Rate</td><td>Weight: $materialName1Weight</td></tr>";

Hopefully that makes sense. As always, very appreciated.

I am trying to post while loop array. But I dont know how to do this and I used foreach and it works for each array but doesnt loop this. My table has Que_ID, Question, choice1, choice2, choice3 and choice 4. I would like to do something like.. For each Que_id (choice1, choice2, choice3 , choice4), this should be looped for each que_id

so far I have

Code: [Select]
$counter = 1;
 while( $info = mysql_fetch_array( $sqll ))
 //))
 {
 echo "{$info['Que_ID']} <br />\n";
echo "<input type='hidden' name=\"Que_ID\" value=\"{$info['Que_ID']}\" /> ";
echo "{$info['Que_Question']} <br />\n";
echo "<input type=\"checkbox\" name=\"choice[$counter]\" value=\"{$info['Que_Choice1']}\" /> ";
echo "{$info['Que_Choice1']} <br />\n";
$counter++;
echo "<input type=\"checkbox\" name=\"choice[$counter]\" value=\"{$info['Que_Choice2']}\" /> ";
echo "{$info['Que_Choice2']} <br />\n";
$counter++;
echo "<input type=\"checkbox\" name=\"choice[$counter]\" value=\"{$info['Que_Choice3']}\" /> ";
echo "{$info['Que_Choice3']} <br />\n";
$counter++;
echo "<input type=\"checkbox\" name=\"choice[$counter]\" value=\"{$info['Que_Choice4']}\" /> ";
echo "{$info['Que_Choice4']} <br />\n";

$counter++;
How would go on to posting these while loop and display Que_ID and all the choices that are ticked for this que_ID and if its not ticked then its 0.

Hello gurus,

I've been pounding my head against the wall on this one.  It must be something simple I'm missing.  I have a text field that posts ($_POST['case_ids']) a comma separated value such as 10067,10076  When I use explode to break it up it should make it an array.  However when I use it in a foreach loop I get an invalid argument error.  If I do a check for is_array() it fails the check. 

If I print the array I get:
Code: [Select]
Array ( [0] => 10067 [1] => 10076 )
So I thought maybe I get the error because the individual array elements don't have commas between them so I wrote this to put commas in between each element except the last:
Code: [Select]
$cases = array();
$numItems = count($case_ids);//get count of array
$i = 0;//initialize counter
foreach($case_ids as $key => $value){
if($i+1 != $numItems) {
$cases[$key] = $value.',';
}else{
$cases[$key] = $value;
}//end if $i+1
$i++;
}
However this new array still gets the invalid argument error.  Are these not valid arrays?

Any help would be greatly appreciated.

Thanks in advance,
Twitch

Hello all!

I can't seem to wrap my head around how to accomplish my problem.  Here's my problem.  I have several array's (only two this example).

Code: [Select]
<?php
$item_num =   array ( 0 => "00000", 1 => "00001", 2 => "00002" ),
                $item_disc =    array ( 0 => "Some info for 0", 1 => "Some info for 1", 2 => "Some info for 2" )
?>

I want to build a table using the arrayed information.  Something like:

Code: [Select]
<table>

   <tr>
      <td><input value="'.$item_num[0].'" name="item[]" size="9"></input></td>
      <td><input value="$item_disc[0]" name="disc[]" size="33"></input></td>
   </tr>

   <tr>
      <td><input value="'.$item_num[1].'" name="item[]" size="9"></input></td>
      <td><input value="$item_disc[1]" name="disc[]" size="33"></input></td>
   </tr>

<table>

I know how to loop through an array but this is a bit different in that I each array would need extracted in the loop.  If you notice I want to build rows and the values for each row are in separate arrays.  So $item_num and $item_disc are in the same row and exacts ['0'] and the next row is [1] and the next row is [2], etc...

Any help would be great.  Thanks.

If I have an array, $array, how can I loop through it (e.g. with a foreach() ) .. but just do it randomly?

So each time, random entries of the array are used and not necessarily in order.

Hi everybody

I am new to arrays, and loops pretty much, so please dont be mean!

I am trying to turn a single upload form into a multiple upload form.  My logic is I need to use arrays and loop the code for uploading the data from the form to the database (for each of these files, create a thumbnail, resize and rename original, move to folder, create path, and insert all that information into the db)

But I have no idea how

I've got this in the form (now) ....
<pick an album to put the files into>
<input type="file" name="image[]" >
<input type="file" name="image[]" >

and this is the code for the whole upload. It worked for single uploads ... but I'm now at a loss ...

The code is abit messy, sorry.  I'm fairly sure I need a foreach loop, but I dont know where to put it

Really Really hoping you can help. Many thanks in advance

HI all,

I need help to get data out of an array using a while loop or something simalar.

What I have, is this:

<?php

$data = array(

  1  => array(
                         "name" => "Jordan Smith",

 "age"    => "16 Years 0 Months"

),
  2  => array(
                        "name" => "Olivia Smith",

                "age"    => "13 Years 12 Months"

)
);

Now, what I did, is I constructed this:

while($result=$data[1]) {
echo $result['name'];
} 

But it echoed "Jordan Smith" for infinity down the page.

If anyone can help be do this, it will be great. Thanks

I am trying to initialize every value in my $errors array to have a value of '' so I don't get "undefined variable" errors!

Here is what I have...

Code: [Select]
//Put in some values and then try to erase them.
$errors = array('firstName' => 'Enter First Name', 'lastName' => 'Enter Last Name');

//Want an initialized array.
foreach($errors as $key => $value){
$key = '';
}

But that doesn't seem to work when I run

Code: [Select]
print_r($errors, true);

Thanks,


Debbie
