Variable within variable name (unexpected T_VARIABLE, expecting ']')

[loyx]

Hey, I'm having trouble when trying to use a variable in a variable name.

 

I get the error Parse error: syntax error, unexpected T_VARIABLE, expecting ']'  when trying to do this:

 

if ($_POST[item_{$x}_num_of_supplies] != '')
...

The $x is a variable for a loop counter. Every time the loop runs I want it to access a different variable, like this:

$_POST[item_1_num_of_supplies]

$_POST[item_2_num_of_supplies]

$_POST[item_3_num_of_supplies]

$_POST[item_4_num_of_supplies]

etc etc

 

I tried putting the variables in single quotes and double quotes, and using the braces in different places but nothing seems to work, producing various errors. Does anyone know a solution?

Might need to see more code, but have you tried:

if ($_POST['Item_{$x}_num_of_supplies'] != '')

or

if ($_POST['Item_'.$x.'_num_of_supplies'] != '')

[chmpdog]

it might work if you removed the "item_x_num_suplies" try having just the variable: "x"

 

so like this

 

$_POST[$X]

 

that will work
