Arrays for form variables?

[martinj]

My PHP book says that it is possible to place arrays variables in form elements.
My first stab at this did not work. Has anyone gottent this to work?

For example:

<input name=arrayvar[] type=text>
<input name=arrayvar[] type=text>

Then the POST routine would be able reference the following:

echo arrayvar[0]."<BR>";
echo arrayvar[1]."<BR>";

Maybe adding quotes like this may help:

<input name="arrayvar[]" type="text">
<input name="arrayvar[]" type="text">

This makes your html more compliant, and since you use []'s they quotes lets the browser know exactly where the input field's name ends.

I think that if you have..

<form>
<input type=array[] value=1>
<input type=array[] value=2>
.
.
</form>

Then to reference array variable you need to
$array[0] $array[1]. (Just like a regular variable).

thats not vaild html.

its..

<input type="text" name="array[]">
<input type="text" name="array[]">

to echo them you..

for ($i = 0; $i < count ($array); $i++) {
echo array[$1];
}

Your form is incorrect. If you give a form input field array[] type of name, then when such variable is submitted to processing script it has to be referenced as an $array.

Output from your code will be

array[0];
array[1];

Instead of a value that these variables hold. The correct form is the one I gave in my first post for this thread.

Thanks for the help folks. The problem was not quoting the array variable name. I got it to work with this format:

Form page:
<input type="text" name="arrayvar[]">
<input type="text" name="arrayvar[]">

Post page:
for($x=0; isset(arrayvar[$x]); $x++)
echo $arrayvar[$x]."<BR>";

Thanks again,
