(Firefox :: General, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; fr-FR; rv:1.7.5) Gecko/20041108 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; fr-FR; rv:1.7.5) Gecko/20041108 Firefox/1.0

The following PHP code doesn't work for FF but should. 
It seems

echo "<input type=\"radio\" name=\"db_id_moyen_paiement\" value=\"2\">A<br>
<input type=\"radio\" name=\"db_id_moyen_paiement\" value=\"3\">B<br>
<input type=\"radio\" name=\"db_id_moyen_paiement\" value=\"4\">C<br>
<input type=\"radio\" name=\"db_id_moyen_paiement\" value=\"5\" CHECKED>D<br>";

It works when I change the name of the input button.

Reproducible: Always

Steps to Reproduce:
1. test PHP code in FF -> NOK
2. change name of input
3. test PHP code in FF -> ok

Actual Results:  
It didn't check the last radio

Expected Results:  
it should have checked the last radio

seems that the name of input is the cause of the problem.
when I changed the name to a shorter one (without _), it worked.

PHP ? Mozilla doesn`t understand PHP, only the HTML output.
Do you have a html testcase (URL) ?

never a blocker

hmmm... seems that restarting FF fixes the issue.
After a while it came back, in a different way (but selecting the wrong radio).

Unfortunately, the code is related to payment and should be kept secure.

i tried to isolate the faulty code, but it seems that it is related to
activity in FF so it doesn't work.

I'll try to capture the result and HTML next time I face it.

Would you care to review Bug 265470 'Reloading a page with POSTed form data will
result in incorrectly "checked" radio buttons' and/or similar bugs concerning
reloading forms.

Does your receipe involve Reloading? Does it involve the POST method?

It may be tedious but you may find it essential to produce a valid test-case
before being sure that what you are seeing is not a dup.

No response from reporter, resolving as WFM. Please reopen if this is still an
issue in a recent trunk build.

No, this does not work. If you have multiple sets of radio buttons and the names have underscore, Firefox gets confused.

Using these names, the Boys and Girls radio buttons are treated separately... both Boys and Girls get checked:

<input name="U11GirlsDisabled" type="radio" value="false" checked="checked">Show U11 Girls
<input name="U11GirlsDisabled" type="radio" value="true">Hide U11 Girls

<input name="U11BoysDisabled" type="radio" value="false" checked="checked">Show U11 Boys
<input name="U11BoysDisabled" type="radio" value="true">Hide U11 Boys

But, if you have underscores, both sets seem to be getting combined... only the Boys is "Checked":

<input name="U11_Girls_Disabled" type="radio" value="false" checked="checked">Show U11 Girls
<input name="U11_Girls_Disabled" type="radio" value="true">Hide U11 Girls

<input name="U11_Boys_Disabled" type="radio" value="false" checked="checked">Show U11 Boys
<input name="U11_Boys_Disabled" type="radio" value="true">Hide U11 Boys


It seems like it's only looking at the name value before the first _... which means it things all 4 radio buttons are named "U11".


This IS a real bug... and a stupid one!
