In my case I'm picking up how many records are inside the variable. But the .length
function determines that when there is only one record it is undefined
, and it should show that there is a record in it. Is this some kind of function error, or is there a way to fix it? Or is there some other method I can use?
I'm storing this way:
function insert_info(){
w_qtde_info = document.forms['my_form'].blc_info.length;
}
<form name="my_form" method="post">
<table width="100%">
<tr>
<td>
<?php
while($w_cont <= $w_opc)
{
print('<input type="radio" name="blc_info" value="">');
}
print('<input type="button" onClick="insert_info();" value=">>">');
?>
</td>
</tr>
</table>
</form>
w_opc is determined by the user. That is, he will add the radios (according to the example) according to the value that the user has determined!
Obs: I took the part of php as a reference for: Text radio
