I have a php file which selects a large amount of data from mutiple sql table. Naturally it takes a long time to complete the whole process. I want to display a progress bar which will express the progress of the script running. How to display a progress bar? The script below shows a portion of the php file.
php //RIGHT(AdmitCode,1), PartCode, MID(AdmitCode,2,2), MID(AdmitCode,1,1) DESC, RollCode $query = "SELECT * FROM students1 ORDER BY PartCode, AdmitCode, yearcode desc, RollCode"; $result = mysql_query($query); // start a table tag in the HTML echo "order='1' align='center' style='border-collapse:collapse' width='110%'>"; echo " List of candidates for Three year Degree (Honours/General) Programme Examination-".$bx1." (".$bx2.") "; //$row['index'] the index here is a field name echo " Sl. No ID Semester Roll No Registration No Name Honours Elective-1 Elective-2 Elective-3 MIL Foundation Soft studies Syllabus "; $ty=0; while($row = mysql_fetch_array($result)){ //Creates a loop to loop through results $ty++; if ($ty%2==0) echo ""; else echo ""; echo "$ty " . $row['StudentID']." " . $row['PartCode']." " . $row['AdmitRollNo'] . " " . $row['RegistrationNo']. " " . $row['Name'] . " " . $row['HonoursSubject'] . " ". $row['ElectiveSubject1'] . " ". $row['ElectiveSubject2'] . " ". $row['ElectiveSubject3'] . " ". $row['MIL'] . " ". $row['Foundation'] . " ". $row['SoftStudies'] . " ". $row['Syllabus'] . " "; } echo ""; //Close the table in HTML
You can use the following simple code
php //header('Content-Type: text/event-stream'); // recommended to prevent caching of event data. header('Cache-Control: no-cache'); //long_process.php for($i=1;$i<=3;$i++){ //do something echo 'processing...'; ob_flush(); flush(); sleep(1); } echo 'CLOSE', 'Process complete'; ?>
Or use as following
html> <html> charset="utf-8" /> /> <input type="button" onClick="startTask()" value="Start Long Task" /> <input type="button" onClick="stopTask();" value="Stop Task" /> /> /> Results /> id="results" style="border:1px solid #000; padding:10px; width:300px; height:250px; overflow:auto; background:#eee;">
