html radio button with an "other" selection that has a text box - php

Question

When my insert runs it will write the text in the text box but if I choose a radio button selection other than "other" nothing is inserted into the table.
If I remove the "other"code the radio button selected is written to the table.
here is the code
<input type="radio" name="job" value="PHP Programmer">PHP Programmer
<input type="radio" name="job" value="SQL Programmer">SQL Programmer<br>
<input type="radio" name="job">Other <input type="text" name="job" >
<h3>* If yes, check which ISO standard(s) you are accredited?</h3>
<input type="radio" name="iso_standard" value="17020">17020
<input type="radio" name="iso_standard" value="17025">17025
<br />
<input action="submit" type="submit" name="submit" value="Submit">
</form>
<?php
if(isset($_POST['job']) && isset($_POST['iso_standard']))
{
$job = mysqli_real_escape_string($db, $_POST['job']);
$iso_standard =mysqli_real_escape_string($db, $_POST['iso_standard']);
$sql="insert into tbl_test_insert(iso_cert, iso_standard)
values ('$job', '$iso_standard')";
if(!mysqli_query($db, $sql))
{
die('Error: ' .mysqli_error($db));
}
echo "1 record added";
}
else
{
echo "You didn't choose all the options!
}
?>

Answer 1

You are overwriting the value of job with the text input field. It does not mather if it has any value or not.
Please rename your <input type="text" name="job" > to for example otherJob and you should be fine
edit:
change <input type="radio" name="job">Other <input type="text" name="job" >
to <input type="radio" name="job" value="other">Other <input type="text" name="otherJob">
change $job = mysqli_real_escape_string($db, $_POST['job']);
to
$job = mysqli_real_escape_string($db, $_POST['job']);
$otherJob = mysqli_real_escape_string($db, $_POST['otherJob']);
if ($job == 'other') {
$jobField = $otherJob;
} else {
$jobField = $job;
}
and change $sql="insert into tbl_test_insert(iso_cert, iso_standard)
values ('$job', '$iso_standard')";
to $sql="insert into tbl_test_insert(iso_cert, iso_standard)
values ('$jobField', '$iso_standard')";
