PHP loop and HTML input fields

[trufla]

Hiya!

I have a loop, which based on a query outputs every image stored in a mysql table, and places them into a form for selection:

<?php
$imagequery = "SELECT * FROM Image";
$result = mysql_query($imagequery) or die("Invalid query: " . mysql_error());

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

?>


<p><img src="<?php echo $row['ImageLoc']; ?>" width="100" height="100" /></p>

Select image <input type="checkbox" name="<?php echo $row['ImageID']; ?>" 

value="<?php echo $row['ImageLoc']; ?>" />

<?php
}

?>

</form>

I have come unstuck because I am not sure how to grab the "ID" or "Loc" in a $_POST array in the next script, which is the info of the actual image a user selects .

I have had a look at session arrays, but I am not sure how to approach this.

Could some help?

You don't need session arrays.

One way to do it is this:

<?php
$imagequery = "SELECT * FROM Image";
$result = mysql_query($imagequery) or die("Invalid query: " . mysql_error());

while ($row = mysql_fetch_array($result)) {
?>
<p><img src="<?php echo $row['ImageLoc']; ?>" width="100" height="100" /></p>

Select image <input type="checkbox" name="image[]" value="<?php echo $row['ImageLoc']; ?>" />

<?php
}
?>
</form>

This way, the checkbox lines will look like this:

<input type="checkbox" name="image[]" value="43" />
<input type="checkbox" name="image[]" value="9" />
<input type="checkbox" name="image[]" value="27" />

Then, on the next page, you can look through the $REQUEST or the $POST variable for "image" like this:

$imagelist = array();
foreach ($_REQUEST as $k=>$v) { if ($k=="image") { $imagelist[] = $v; } }
print_r($imagelist);

Why thank you!

Could I ask one quick question:

how can I display a single index, i.e. echo $imagelist[0];

This simply displays "Array", not the value of the zero index.

Cheers!

Do excuse me!

Ahem, just discovered interpolation:

echo "The image you chose was: {$imagelist['0'][0]}\n";
