The form in html file below:

<form name="myform" method="post" action="yuhuu.php">
<input type="text" name="text[1]">
<input type="text" name="text[2]">
<input type="text" name="text[3]">
<input type="text" name="text[4]">
<input type="submit" name="submit" value="Send">
</form>

i'm sure the variable that receive by yuhuu.php is array.
But how if my form like below and i need the value add to other variable with array type ? And the name of variable is $text.($text is array)

<form name="myform" method="post" action="yuhuu.php">
<input type="text" name="text1">
<input type="text" name="text2">
<input type="text" name="text3">
<input type="text" name="text4">
<input type="submit" name="submit" value="Send">
</form>

If you use name="text[1]" then the array will be called text and element 1 will have the value of the HTML form field.

No problem.

If you already have an array called text with some elements there, I think you should be able to do ...

<form name="myform" method="post" action="yuhuu.php">
<input type="text" name="text[]">
<input type="text" name="text[]">
<input type="text" name="text[]">
<input type="text" name="text[]">
<input type="submit" name="submit" value="Send">
</form>


This will add the entries onto the end of the array for you.

Regards,

Richard Quadling.

you all rigth.
But I need the modification not in the form file. I need the resolve in yuhuu.php.

yuhuu.php still receive $text1, $text2, $text3 and $text4. And it will create new variable with name $text in array type. Each variable from form (last form in my question)will add to each variable in array variable.

$text1 -> $text[1]
$text2 -> $text[2]
$text3 -> $text[3]
$text4 -> $text[4]

is it possible ?

I already read in manual about variable variables. I see something relate in there. But my head still spin :(

the reason why i need the form still like that, because i need change the value in each text box with javascript. If the name the text box in array, javascript tell me the text box not 'object'. So I try modify the php file.

below the javascript to use:

<script>
function checkAll()
{
  for (var j = 1; j <= 2; j++)
   {
      box = eval("document.mydocument.text" + j );
      if (box.value == "") box.value = "yuhuu";
   }
  for (var i = 1; i <= 2; i++)
   {
      box = eval("document.mydocument.text" + i );
      if (box.value == "") box.value = "yihaa";
   }
}

This is the code in PHP :


$i=1;
while (isset(${"text".$i})) {
    $text[$i] = ${"text".$i};
    $i++;
}
