Post form values as array

[BigBadDave]

Hi, How do you post form values as an array? In PHP I would do it like this:

<?php

for ($i = 0; $i < 5; $i++) {
    echo &quot;<input name='foo[]'>&quot;;
}

?>

Then I could read the posted results back like this:

<?php

for ($i = 0; $i < count ($_POST[&quot;foo&quot;]); $i++) {
    echo &quot;Result of foo $i is: &quot; . $_POST[&quot;foo&quot;][$i];
}

?>

How do I do this with Cold Fusion Regards

I havn't really explained myself, what I mean is:

<input name='foo[]' value=&quot;one&quot;>
<input name='foo[]' value=&quot;two&quot;>
<input name='foo[]' value=&quot;three&quot;>
<input name='foo[]' value=&quot;four&quot;>
<input name='foo[]' value=&quot;five&quot;>

Then I could read the posted results back like this:

<?php

for ($i = 0; $i < count ($_POST[&quot;foo&quot;]); $i++) {
    echo &quot;Result of foo $i is: &quot; . $_POST[&quot;foo&quot;][$i];
}

?>

I'm not sure that you can replicate the array you depict (I'm not even sure it's valid HTML)... but what you can do is simply append a number dynamically to the field name, like:

<!--- value list would come from whatever source you need.
      this list is just for example purposes --->
<CFSET myValueList = &quot;one,two,three,four,five&quot;>
<CFOUTPUT>
<FORM action=&quot;...&quot; METHOD=&quot;POST&quot;>
  <CFLOOP index=&quot;whichField&quot; from=&quot;1&quot; to=&quot;5&quot;>
    <INPUT name=&quot;foo#whichField#&quot; value=&quot;#ListGetAt(myValueList,whichField)#&quot;>
  </CFLOOP>
  <input type=&quot;submit&quot; name=&quot;submit&quot; id=&quot;submit&quot; />
  </FORM>
</CFOUTPUT>

then your action page can dynamically pull the values like:

<CFOUTPUT>
<CFLOOP index=&quot;whichField&quot; from=&quot;1&quot; to=&quot;5&quot;>
  Result of foo #whichField# is: #FORM[&quot;foo&quot; & whichField]#<br />
</CFLOOP>
</CFOUTPUT>

Would that do it for you?

Hope it helps,

Yeah thanks that works, but now how do I loop an SQL update? like this:

<cfloop index=&quot;i&quot; from=&quot;1&quot; to=&quot;#form.arrTotal#&quot;>
  <cfquery name=&quot;update#i#&quot; datasource=&quot;ema&quot;>
    #PreserveSingleQuotes (sql[i])#
  </cfquery>
</cfloop>

That dosn't work how do I do it? Regards

What does your "sql" array look like?
Hope it helps,
