[Resolved] DISABLED form fields ?

Rodders

I have a form which is used to update a single MySQL table.

The form has 7 fields, the first of which is not to be edited but I need the value of the field as it is the key to my table.

The other 6 fields are pulled from the DB and if they are already populated (ie. NOT ZERO) then they too will be visible but disabled.

However, when I submit this form the DISABLED form fields are not passed to the PHP script.

Is there a simple way around this or do I have to mess about with hidden fields etc ??

Regards

Could you post some code?

Here is the form....

<FORM METHOD=POST ACTION='/form.php'>

<TABLE>

<TR>
<TD width="139"><strong><font color="#000000" size="3">Your Name :</font></strong></TD>
<TD width="464"><strong><font color="#000000" size="-1">
<INPUT TYPE=TEXT NAME='SubTeam' VALUE='MARTIN GODDARD' DISABLED>
</TD>
</TR>

<TR>
<TD><strong><font color="#FFFF80" size="3">Old ID - 1:</font></strong></TD>
<TD><strong><font color="#000000" size="3">
<INPUT TYPE=TEXT NAME='old_id_1' SIZE=24 MAXLENGTH=4 DISABLED VALUE='123'>
</TR>

<TR>
<TD><strong><font color="#FFFF80" size="3">New ID - 1:</font></strong></TD>
<TD><strong><font color="#000000" size="3">
<INPUT TYPE=TEXT NAME='new_id_1' SIZE=24 MAXLENGTH=4 VALUE=''>
</TR>

<TR>
<TD><strong><font color="#FFFF80" size="3">Old ID - 2:</font></strong></TD>
<TD><strong><font color="#000000" size="3">
<INPUT TYPE=TEXT NAME='old_id_2' SIZE=24 MAXLENGTH=4 VALUE=''>
</TR>

<TR>
<TD><strong><font color="#FFFF80" size="3">New ID - 2:</font></strong></TD>
<TD><strong><font color="#000000" size="3">
<INPUT TYPE=TEXT NAME='new_id_2' SIZE=24 MAXLENGTH=4 VALUE=''>
</TR>

<TR>
<TD><strong><font color="#FFFF80" size="3">Old ID - 3:</font></strong></TD>
<TD><strong><font color="#000000" size="3">
<INPUT TYPE=TEXT NAME='old_id_3' SIZE=24 MAXLENGTH=4 VALUE=''>
</TR>

<TR>
<TD><strong><font color="#FFFF80" size="3">New ID - 3:</font></strong></TD>
<TD><strong><font color="#000000" size="3">
<INPUT TYPE=TEXT NAME='new_id_3' SIZE=24 MAXLENGTH=4 VALUE=''>
</TR>

</TABLE>

<P>

<INPUT TYPE=SUBMIT NAME='Save' VALUE='Submit your changes'>

</FORM>

And here is the script that shows me the values in $_POST array

if (isset($_POST['Save'])) {
	echo "THE SUBS HAVE BEEN SAVED, SO UPDATE THE WHOLE ROW";
	print_r ($_POST);
}

once field is already disabled it wont pass any value, disabled field is not even sent if the form is submitted

so in case you disabled a field in your form try adding a hidden field so it will pass the value your hidden field name should be the same as your field name

Add a readonly attribute. (Note, this will only work in an input that is text type. (Also, I encourage you to follow the HTML/XML standards for quoting your attributes... Get into and stay in the habit. It will save you from having headaches later.

Ref: W3Schools

Many Thanks to you all for your information.

Especially thanks to TheDefender for giving me exactly what I needed, I was sure that such a thing existed but didn't know where to look.

As for the HTML/XML standards, I am in a process of trying to modify my site to use XML standards - although this piece of code is for a friend so for that reason I prefer to just advise him of the benefits.

On that subject, TheDefender's attribute should have been written readonly="readonly". HTML4.01 allows attributes with no values, but XHTML1.0 isn't as lenient (being a dialect of XML, which isn't, either).

When it comes to quoting attributes in HTML, the official word is that "In certain cases, authors may specify the value of an attribute without any quotation marks. The attribute value may only contain letters (a-z and A-Z), digits (0-9), hyphens (ASCII decimal 45), periods (ASCII decimal 46), underscores (ASCII decimal 95), and colons (ASCII decimal 58). We recommend using quotation marks even when it is possible to eliminate them."

I stand corrected. 😉 I always appreciate it!

I'm such an amateur that I forget to check the standards at w3.org when doing these things. I'm hoping that this is the final kick up the backside I need to make me do it every time in future.

Nice to see Weedpacket is still here giving ace advice just like when I first registered a couple of years ago.
