Editable array through a form? Please help!

brianb

Hello,

Looking to edit my ARRAY variables through a form. Of course each ARRAY variable is tied to the other variables as well. I'd like to be able to edit each chunk. (For instance...if I want to edit variable 3 a form would be displayed to edit image_3.jpg, Headline 3, Caption 3, and Link 3)

Can anyone gives me some ideas on how to do so? I dont't ever know where to start.

Here's my array:

<?php

$image = Array(
 "image_1.jpg",
 "image_2.jpg",
 "image_3.jpg",
 "image_4.jpg",
 "image_5.jpg"
 );

$headline = Array(
"Headline 1",
"Headline 2",
"Headline 3",
"Headline 4",
"Headline 5"
);


$caption = Array(
"Caption 1",
"Caption 2",
"Caption 3",
"Caption 4",
"Caption 5"
);

$link = Array(
"Link 1",
"Link 2",
"Link 3",
"Link 4",
"Link 5"
);


$many = count($headline);
$x = rand(0,$many-1);

echo "<table width='100%' border=0 cellspacing=0 cellpadding=3><tr><td width='0%'><a href='".$link[$x]."' class='images'><img src='/temp/main/".$image[$x]."' width='130' height='60' border='1' alt='".$headline[$x]."'></a></td><td width='100%'><p><a href='".$link[$x]."' class='main5'><u>".$headline[$x]."</u></a><br>".$caption[$x]."</td></tr></table>";

?>

how/where are you storing this array? it would appear that you are using an array to mimic the functionlity of a database. you should really consider using an actual database instead, especially if you are going to need to update it frequently.

anyway, if you must use an array, I might suggest that use a 2D array instead (for organization):

$array = array (
1 => array ('image' => 'image_1.jpg', 'headline' => 'Headline 1', 'caption' => 'Caption 1', 'link' => 'Link 1'),
2 => array ('image' => 'image_2.jpg', 'headline' => 'Headline 2', 'caption' => 'Caption 2', 'link' => 'Link 2'),
...etc...

then you can refer to your array indexes like:
$array[$x]['image'], $array[$x]['headline']

hey Devin,

Thanks for the reply...

So, I tried this:

<?php

$array = array(

1 => array ('image' => 'image1.jpg', 'headline' => 'headline 1', 'caption' => 'Caption 1', 'link' => '/movies/film.php?filmID=287'),
2 => array ('image' => 'image2.jpg', 'headline' => 'headline 2', 'caption' => 'Caption 2', 'link' => '/movies/film.php?filmID=350'),
3 => array ('image' => 'image3.jpg', 'headline' => 'headline 3', 'caption' => 'Caption 3', 'link' => '/news/news.php?id=839'),
4 => array ('image' => 'image4.jpg', 'headline' => 'headline 4', 'caption' => 'Caption 4', 'link' => '/movies/film.php?filmID=109'),
5 => array ('image' => 'image5.jpg', 'headline' => 'headline 5', 'caption' => 'Caption 5', 'link' => '/news/news.php?id=812')
);

$many = count($array);
$x = rand(0,$many-1);

echo "<table width='100%' border=0 cellspacing=0 cellpadding=3><tr><td width='0%'><a href='".$array[$x]['link']."' class='images'><img src='/temp/main/".$array[$x]['image']."' width='130' height='60' border='1' alt='".$array[$x]['headline']."'></a></td><td width='100%'><p><a href='".$array[$x]['link']."' class='main5'><u>".$array[$x]['headline']."</u></a><br>".$array[$x]['caption']."</td></tr></table>";

?>

...now for some reason, one of the variables isn't being shown....it shows up and blank and broken. Any ideas why this would be happening?

Thanks for the help in advance.

may it be the indexing used here, starting with 1 instead of 0 as arrays normally would?

if so, $x = rand(1,$many); might fix the problem.

That was it! Thanks for the help!
