foreach loop

[anfetienne]

is it possible to have more than 1 array on a foreach loop?

[TheServant]

What do you mean? Post a sample code so we can see what you're trying to do.

[zabsmarty]

yes, by adding array from while loop

[zabsmarty]

Try to use while loop for getting array

[anfetienne]

how would i use the while loop to add the extra array to a foreach loop?

at 1st i thought id have to to the array_combine.....that way i can make an extra key and value using the 2 arrays i need. But i still can't figure how to get the extra item into the foreach....once i combined my arrays i tried this

$details = array_combine($_POST['photoT'], $_POST['captionT']);

// Loop through the POST items
foreach ( (($_POST['picT'] as $picT => $picStart)) && ($details as $photoName => $picCaption)) )

{

$nameCapsA = $xmlobj->addChild($picStart);
$nameCapsA->addAttribute("name", $photoName);
$nameCapsA->addAttribute("caption", $picCaption);

}

You can only use 1 array as a foreach() loop's argument.

Am I right in thinking the amount of files you upload will be the same as the amount of captions you have?

The reason I suggested you do it all in one loop, is because (if you are having the same number of items -- above) you could use the array key given from the foreach loop to access the same index of a different array.

Consider this:

$array_1 = array ( 1, 2, 3, 4, 5, 6 );
$array_2 = array ( "one", "two", "three", "four", "five", "six" );
 
foreach ( $array_1 as $key => $value )
{
    echo "{$value} = {$array_2[$key]}<br />";
}
// Produces:
// 1 = one
// 2 = two
// ... etc.
 

[anfetienne]

yes you are right in suggesting that but as i have three arrays it's not that easy......ahhhhh but?

what if i have a while loop to generate one and and the use a foreach loop within the while loop for the $key & $value...would that work better? I will do a test and post my code here

[anfetienne]

also please bare in mind this is being used towards simpleXML.....it doesn't always take php coding as it should once output.......such a pain

[Markus]

Do you mean you have a multi-dimensional array, or 3 seperate arrays?

Can I please see your upload form; I can't make sense of what's happening here.

[anfetienne]

the form fields are generated with php, below is what is generated. I'm trying to make an array that can be used within the foreach....i dont really know how many arrays I need but i have 3 picT, photoT, captionT.....i've named the fields picT[] photoT[] and captionT[] as to use them as an array when i generate the xml file



code....

            echo '<td><center><p><a href="'.$img_path .'"><img src= "'.$path.$item[$n] .'" height="100" width="100"></a></p></center>';
            echo '<center><p><input type="hidden" name="picT[]" value="pic'.$pn++.'"/></p></center>';
            echo '<center><p><input type="hidden" name="photoT[]" value="PHOTO '.$pto++.'"/></p></center>';
            echo '<center><p><input type="text" name="captionT[]" value=""/></p></center>';
            echo "<center><p><a href=imgEdit.php?img=$img_path> > Edit Image < </a></p></center><br></td>";
 

[anfetienne]

for some reason simpleXML wouldn't read the values that were brought in normally through post thus why i've had to use the foreach loop......

if i can't have more than 1 array within the foreach can i combine the 3 so i can use the within the loop?

[Markus]

Like I said before, you can loop through one array using foreach() loop, and then use the key given to you, to access the same index in the other arrays.

 
foreach ( $_POST['picT'] as $key => $value )
{
    // use $key to access the other elements.
    echo $value . "<br />";
    echo $_POST['photoT'][$key] . "<br />";
    echo $_POST['captionT'][$key] . "<br />";
 
    // Do something with your xml object
    $child = $xml->addChild( $value );
    $child->addAttribute( 'name', $_POST['photoT'][$key] );
    $child->addAttribute( 'caption', $_POST['captionT'][key] );
}

ahhhhhh i definately see what you are saying now markus.......thanks for that I am going to test this, write it down and practice it so i understand it more.

Thanks again

[anfetienne]

here is the result......

Notice: Undefined variable: xml in /home/vecre0/public_html/test/8/xmltest.php on line 21

Fatal error: Call to a member function addChild() on a non-object in /home/vecre0/public_html/test/8/xmltest.php on line 21

[Markus]

Yeah, you're going to have to use your xml object - the one you've shown in previous threads.

[Markus]

I should mention that your arrays aren't necessarily going to be the same length, some may be shorter, some may be longer. In an ideal world, we would be fine assuming they are the same, but, alas, we aren't, so you should incorporate some checks into your code to prevent any errors.

- Mark.

[anfetienne]

hi markus.....ive tested it with the different lengths of values stored in the arrays varying from 1 character to 250 characters and i get no errors at all.....thanks again

[anfetienne]

Here feel free to test the upload sequence @

http://ve-creative.com/test/8/templates.php

Once images are uploaded you can view their directory @

http://ve-creative.com/test/8/upload/randomdigit (please copy and paste the random digit generated on the first page and paste where "randomdigit")

Uploaded images are shown on the edit page.....please feel free to test the captions form underneath the images and click submit

the xml file created can be found @
http://ve-creative.com/test/8/xmlf (you can download the xml to see what is generated)

[Markus]

Looks like it is all working.

Couple of ideas: if an image has a caption, it would be useful to see that caption in it's caption input area. Currently, when you add captions, the inputs remain blank.

Also, your submit buttons, when not hovered over, appear 'disabled'. If you've ever seen a disabled form element, they have a greyish overlay, like your normal buttons do. This may be distracting.

And congrats.

[anfetienne]

loool i know exactly what you are saying but I can only work to what a client asks for and its not to distract people from their main objective.

Right now I am just sorting out how I want to structure my database for this app....once i've got my structure I will be adding in the captions so people can view it once they saved them
