Textfields in loop.. how can you find their values

[Anon]

Hi All

I am generating textfields in loop and the name of my text field is:
link-$group_id-$topic_id[$i]. The problem is that I cannot fetch the values of the loop-generated textfields in the next function. The link variable becomes something like $link-7-2 which holds the last value of the last textfield. All the other values are lost. How can I get all the values?? Any ideas??

thanks

Save them into an array as you are generating the input fields:

$inp_fields = array();

while (still drawing a input field) {
$inp_fields[] = $link-$group_id-$topic_id[$i];
// draw input field...etc.
}

// now you have everthing in $inp_fields, so just iterate through the array:

reset($inp_fields);

foreach ($inp_fields as $k => $v) {
// Display all the text field names
echo "$k => $v <br>";
}

Hello Beau

I tried to use the way you suggested. I got "Fatal error: Unsupported operand types in /home/www/netpro/netpro1.1/center_setup.php on line 245"
error message and I do not understand why?. Line 245 is $inp_fields = $link-$group_id-$topic_id[$i]; and it is complaining about that. What could be wrong? Why do I get that error message??
Below is part of the code...

while($row4 = mysql_fetch_array($result4)){ 
 $topic_id[] = $row4["topic_id"];
 $topic_name[] = $row4["name"]; 
 $common_deadline[] = $row4["common_deadline"];

}

$inp_fields = array();

for($i = 0; $i < count($topic_name); $i++){

$inp_fields = $link-$group_id-$topic_id[$i];

echo ("<TR bgcolor='#FFFFFF'>\n");
echo ("<td width='64' height='28'><font size='1' face='Arial, Helvetica'>$topic_name[$i]</font></td> \n");

echo ("<td width='60'><input TYPE='text' NAME='link-$group_id-$topic_id[$i]' value='$common_deadline[$i]' size='10'></td>\n");
echo ("<td width='50'>&nbsp;&nbsp;&nbsp;</font></td> \n");

Thanks again

Hi

I try to use an array in this way:

$inp_fields[] = $link-$group_id-$topic_id[$i];

I got this error:

Fatal error: Unsupported operand types in /home/www/netpro/netpro1.1/center_setup.php on line 245

why? what is wrong? The $link-$group_id-$topic_id[$i] is the name of my textfields which are generated in loop. I am collecting this in the $inp_fields[] so that I can get access to their values in the next function. Someone here suggested that approach to me but it is not working anyway. what caused that error???
