help...dynamic form POST

[Anon]

trying to use access the submitted form variables, which use the fieldnames from a mysql database, but I can't figure out how to create a dynamic variable named as the field name from the database.

Check it out. All i get is a blank value after receiving the data from a POST.

example:

fieldname = id

I need a variable called $id so that I can correctly access the value from the submitted form.

Anyone? Thanks for the help.

$fieldname="id";

$$fieldname is the same as $id

read up on variable variables at php.net

I have tried that, but all i get is a blank value for $$fieldname. Code is below using $UpdateFieldName to get field, and trying to use $$UpdateFieldName to access the variable. Will this not work? Trying to pull information from a form, had similiar problems using an array, as php did not see it as an array.

//from first part of page

$MainFields = mysql_list_fields($MainDBName, $MainTable, $link);

$MainColumns = mysql_num_fields $MainFields);

//in the test statement, one day to be used in insert/update

for ($nColumnsCounter = 0; $nColumnsCounter < $MainColumns; $nColumnsCounter++)
{ $UpdateFieldName = mysql_field_name($MainFields, $nColumnsCounter);

echo $$UpdateFieldName ."<br />\n";
}

...(banging head here)
actually, let me take that back, it IS working now, I had an extra "'" in the name of the form element,which led to the name not appearing as I thought it was going to.

THANKS for the help, been screwing with various combinations of this ideas for a few days now, and you are the first one to offer some help!
