problem with array

tariel

Hello!

I'm working on one script for getting the ratings. One part of seems not to work properly:

 $output .= "<tr class='ntext'>
<td colspan='3' bgcolor='$bgcolor'>".$row["student_name"]."</td>
<td bgcolor='$bgcolor' height='24' align='center'> 
<INPUT TYPE='HIDDEN' name='id[".$coach_id."]' value='".$coach_id."'>
<INPUT TYPE='HIDDEN' name='ratings[".$rating_id."]' value='$rating_id'>\n";

Coach_id is retrieved from the database.
It seems that the arrays "id" and
"ratings" don't get any values. And therefore after submitting i get this error for the mentioned above line:"Warning: Invalid argument supplied for foreach() in..."

It seems that the problem might be that i shouldn't use double quotes for example here:name='id[".$coach_id."]'

I tried without them, it didn't help.
So i'm lost now. Anyone can give an idea what might be the trouble?

i don't think you can use sth like array[name] as a name for a form-field

instead use either name=id value=your_value
or if you need it as an array
name=id[] value=your_value

this creates only an numeric array, called
with $array[0] etc.

Thank you, ir4z0r, for the help. But for some weird reason it still doesn't work.
When i checked the contents of array "id" it was just 'array'. 🙁

It's so strange, cause first when i was testing the code everything was working fine. But when i moved the code to where it should be located on the server, it stopped working, though i didn't change anything except for some paths.

Oh, i found the problem. Actualy it was not a in array syntax, but in some other function which was in common functions.
But thanks anyways! Feels so good now.🙂
