Loop Help

[Sleeper]

I have a script im building and I am explorering the loop option for the first time. now I have 3 differnt fields that will need to loop such as $a1 -$b1 -$c1 that I want to loop to $a2 $b2 $c2 and so on down the rows. Now I can do the

 

for ( $counter = 1; $counter <= 40; $counter += 1)

 

to get the numbers from 1-40 or what ever I set there but how to I get the echo to add $a to the 1,2,3.....?

 

I though I could do

 

echo "<input type=\"text\" value='$a$counter' name=\"a$counter\" size=\"10\">";

 

but the $a is not a valid optoin so it skips over it. So how do I get those to wright as $a1 and pull the value for $a1 and keep looping?

why not use an array ?

ie

   echo "<input type=\"text\" value='a[]' name=\"a[]\" size=\"10\">";

then

print_r($_POST['a']);

Cause ive never used arrays before Im still learning here...lol but Im not sure how that dose the job... here is the full coding I have now with your [] in there and its erroring...

 

<?php

include ("inc/config.php");

include ("inc/data_djnames.php");

 

print_r($_POST['djnamefc']);

 

echo "<table border=\"2\" align=\"center\" width=\"383\" bordercolor=\"#000000\" >";

echo "<tr><th>DJ Name</th>";

echo "<th>DJ#</th>";

echo "<th>DJ Color</th></tr>";

for ( $counter = 1; $counter <= 40; $counter += 1) {

echo "<tr><td>";

echo $counter;

echo "</td><td width=78>";

    echo "<font class=\"djname2\">DJ #$counter</font>";

echo "</td><td width=78 >";

echo "<input type=\"text\" value='$djnamefc[]' name=\"djnamefc$counter\" size=\"10\">";

echo "</td></tr>";

}

echo "</table>";

 

?>

 

and im getting

Parse error: syntax error, unexpected ']', expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/hookah17/public_html/timesheet/admin/test.php on line 17

[MadTechie]

your need to escape the brackets (square brackets)

 

try this (untested)

<?php
include ("inc/config.php");
include ("inc/data_djnames.php");

print_r($_POST['djnamefc']);

echo "<table border=\"2\" align=\"center\" width=\"383\" bordercolor=\"#000000\" >";
echo "<tr><th>DJ Name</th>";
echo "<th>DJ#</th>";
echo "<th>DJ Color</th></tr>";
for ( $counter = 1; $counter <= 40; $counter += 1) {
   echo "<tr><td>";
   echo $counter;
   echo "</td><td width=78>";
    echo "<font class=\"djname2\">DJ #$counter</font>";
   echo "</td><td width=78 >";
   echo '<input type="text" value="'.$_POST['djnamefc'][$counter].'" name="djnamefc['.$counter.']" size="10">';
   echo "</td></tr>";
}
echo "</table>";

?>

do you mean

<?php
$arr = array('fname','lname','email');

for ($row=1; $row<=9; $row++)
{
    for ($col=0; $col < 3; $col++)
    {
        echo "<input type='text' name='{$arr[$col]}[$row]' value='{$arr[$col]}$row'> \n";
    }
    echo "\n<br/>\n";
}
?>

ok that ends up giving a value=""

 

See the data_djnames.php will have the color value of $djnamefc1, $djnamefc2 and so on.

 

So I just need the value="$djnamefc#" to be able to pull in the info so I need to be able to do have the vaule = $djnamefc1, $djnamefc2 and so on.

[MadTechie]

the code i posted to should call the values like so

 

echo $_POST['djnamefc'][1];

echo $_POST['djnamefc'][2];

etc

but i'll leave you in Barand wise hands, i'm off to bed .... need sleep

[Sleeper]

ok if I go back and make all my values to $djnamefc[1] then I can do

 

   echo "<input type=text value='$djnamefc[$counter]' name='djnamefc$counter' size=10>";

 

And its pulls up the info. is this the only way? cause if so I hve to go back and change all the coding for every one of those var's

Nevermind that will work just fine. Thanks for the help.
