Mixing Javascript & PHP arrays problem

Drax

I seem to be having a problem with javascript operating on PHP arrays.

The code is written in PHP. As an example, Ihave 3 text fields on a page like such:
[PHP]echo("<input type=\"text\" name=\"field[0]\"......>");
echo("<input type=\"text\" name=\"field[1]\"......>");
echo("<input type=\"text\" name=\"field[2]\"......>")[/PHP]
I can then read in the POSTed values at the start of the script like this before performing data validation.
[PHP]$field = isset($field) ? $field : NULL;[/PHP]
My problem occurs when I want to reference the field using javascript. I think it is because the field name already contains square brackets.

For example, I want a button on each field which will set the field value to todays date, So the following code is added to the <input> definition, where todaybutton() is a function that returns today's date.

[PHP]onclick=\"document.form.field[0].value=todaybutton()"[/PHP]

This doesn't seem to work properly!

I can work around by using fieldnames such as 'field0', 'field1' etc... and reference it as onclick=\"document.form.field0.value=todaybutton(), but it requires extra code getting POST values etc.

Any ideas? Much appreciated!

Yeah, tis a bit of a collision.

Try using the ID attribute for Javascript names and the NAME attribute for PHP names, so for e.g.
[PHP]echo("<input type=\"text\" id=\"field0\" name=\"field[0]\"......>");
echo("<input type=\"text\" id=\"field1\" name=\"field[1]\"......>");
echo("<input type=\"text\" id=\"field2\" name=\"field[2]\"......>")[/PHP]

The you can use the getElementById reference to access the input boxen:
[HTML]onclick="document.getElementById('field0').value=todaybutton()"[/HTML]

This should prevent the PHP and Javascript variables from clashing.

Thanks Seamus - I'll give that a go...
