如何在PHP中使用URL中的值

Question

I am currently making a report error form that has 4 fields:

1. Job ID $jobid
2. Part ID part_id
3. Machine
4. Note

The user clicks on a table corresponding the their work and are brought to a new page with a url that has variable. At the moment all the fields are empty however I want the fields to be populated automatically except for notes.

Current Model

Link to report error form:

$EM_html = '<a href="/report_error_form.php?JobID='.$jobid.'&Machine=EM&PartID='.$part_id.'">'.$tick.'</a>

Report error form:

<form action="" method="post">
        Job Number: <input type="text" value="<?php print ($jobid) ?>" name="jobNum"><br>
        Part Number: <input type="text" value="<?php print ($part_id) ?>" name="partNum"><br>
        Machine Code: <input type="text" name="machCode"><br>
        Note:<br><textarea rows="5" name="note" cols="30" placeholder="More detail... (Is there a way to recreate the error?)"></textarea><br>
        <input type="submit" name="submit" value="Submit">
</form>

Example URL

http://sra-pstest/report_error_form.php?JobID=KANBAN16-09-04-01&Machine=EM&PartID=124047 How do "extract" the information out of the url (JobID, Machine, PartID) and automatically fill out the form?

Answer 1

Please try this

<?php
        $jobid    = @$_REQUEST['JobID'];
        $part_id  = @$_REQUEST['PartID'];
        $machCode = @$_REQUEST['Machine'];
 ?>


    <form action="" method="post">
                Job Number: <input type="text" value="<?php print ($jobid) ?>" name="jobNum"><br>
                Part Number: <input type="text" value="<?php print ($part_id) ?>" name="partNum"><br>
                Machine Code: <input type="text" name="machCode"><br>
                Note:<br><textarea rows="5" name="note" cols="30" placeholder="More detail... (Is there a way to recreate the error?)"></textarea><br>
                <input type="submit" name="submit" value="Submit">
    </form>
