huck Posted March 31, 2014 Share Posted March 31, 2014 Hi Folks There is a bit of code I am struggling to grasp. It is used to print a range of data based on a custom date range. function print_log_selector_form_range($selectedfromdate='today', $selectedtodate='today', $logformat='showashtml') { global $USER, $CFG; $strftimedate = get_string("strftimedate"); $strftimedaydate = get_string("strftimedaydate"); // Prepare the list of action options. $actions = array( 'view' => get_string('view'), 'add' => get_string('add'), 'update' => get_string('update'), 'delete' => get_string('delete'), '-view' => get_string('allchanges') ); // Get all the possible dates // Note that we are keeping track of real (GMT) time and user time // User time is only used in displays - all calcs and passing is GMT $timenow = time(); // GMT //echo "<br />"; // What day is it now for the user, and when is midnight that day (in GMT). $timemidnight = $today = usergetmidnight($timenow); //echo "<br />"; // Put today up the top of the list $dates = array("$timemidnight" => get_string("today").", ".userdate($timenow, $strftimedate) ); $numdates = 1; while ($timemidnight > $COURSE->startdate and $numdates < 365) { $timemidnight = $timemidnight - 86400; $timenow = $timenow - 86400; $dates["$timemidnight"] = userdate($timenow, $strftimedaydate); $numdates++; } if ($selecteddate == "today") { $selecteddate = $today; } echo "<form class=\"logselectform\" action=\"$CFG->wwwroot/admin/report/mentorprogress/index.php\" method=\"get\">\n"; echo "<div>\n"; echo "<input type=\"hidden\" name=\"chooselog\" value=\"1\" />\n"; // echo html_writer::select($options, $name, $selected, array($nothingvalue=>$nothing), $attributes); //choose_from_menu ($dates, "fromdate", $selectedfromdate, get_string("alldays")); //~ print "<pre>"; //~ print_r($dates); //~ print "</pre>"; echo $selectedfromdate; echo "<br />"; echo $selectedtodate; echo "<br />"; echo html_writer::select($dates, "fromdate",$selectedfromdate, get_string("alldays")); // choose_from_menu ($dates, "todate", $selectedtodate, get_string("alldays")); echo html_writer::select($dates,"todate",$selectedtodate, get_string("alldays")); $logformats = array('showashtml' => get_string('displayonpage'), 'downloadasexcel' => get_string('downloadexcel')); //choose_from_menu ($logformats, 'logformat', $logformat, false); echo html_writer::select($logformats, 'logformat', $logformat, false); echo '<input type="submit" value="'.get_string('gettheselogs').'" />'; echo '</div>'; echo '</form>'; } This function above is in lib.php, and is called from index.php via this function: //echo $fromdate; //echo $todate; print_log_selector_form_range($fromdate, $todate, $logformat); //echo $fromdate; //echo $todate; if($logformat == 'showashtml'){ print_overview_table($users, $fromdate, $todate); } I check the dates before and after this function is called and the dates remain at zero, even after selecting valid date ranges. By printing the array to screen I can see that the $dates array has valid entries. The function "print_overview_table" below "print_log_selector_form_range" is supposed to print the valid range to the screen. function print_overview_table($users, $fromdate, $todate){ //check data if(!$users){ die('No Records To Display.'); } //$users = get_mentor_users($DB, $fromdate, $todate, $sumpcat); //~ print "<pre>"; //~ print_r($users); //~ print "</pre>"; //start table echo '<br><br><table class="logtable generalbox boxaligncenter" width="95%" border="1" cellspacing="0" cellpadding="5" style="padding:2px;">'; //add report name echo '<tr><td colspan="5">Admin Report - Mentor Marking Progress</td></tr>'; //add report headings echo '<tr> <th>Mentor</th> <th>Total Summative marked</th> <th>Competent</th> <th>Not Yet Competent</th> </tr>'; //populate //foreach($users as $user){ foreach($users as $key => $user) { /*[id] => 2 [totalmarked] => 1 [totalcommarked] => 1 [totalsummarked] => 0 [markedcompetent] => 1 [markedincompetent] => 0 * */ echo '<tr>'; //echo "<td><a href=\"viewdash.php?mentor=$user->id&todate=$todate&fromdate=$fromdate\">", get_mentor_name($DB, $users[$key]->id),"</a></td>"; echo "<td><a href=\"viewdash.php?mentor=$user->id&todate=$todate&fromdate=$fromdate\">", $users[$key]->firstname ,' ',$users[$key]->lastname,"</a></td>"; echo "<td>",$users[$key]->totalsummarked,"</td>"; echo "<td>",$users[$key]->markedcompetent,"</td>"; echo "<td>",$users[$key]->markedincompetent,"</td>"; echo '</tr>'; } //end table echo '</table><br><br>'; } When a user submits the date ranges the page goes blank. Can anyone give me some pointers to fix this. Quote Link to comment https://forums.phpfreaks.com/topic/287408-form-usage-in-php/ Share on other sites More sharing options...
ginerjm Posted March 31, 2014 Share Posted March 31, 2014 If the page goes blank, check for php errors. Turn on error checking and see what they are. Quote Link to comment https://forums.phpfreaks.com/topic/287408-form-usage-in-php/#findComment-1474491 Share on other sites More sharing options...
maxxd Posted March 31, 2014 Share Posted March 31, 2014 Right off the top, I don't see where you're declaring $selecteddate. You've got $selectedfromdate and $selectedtodate as parameters of print_log_selector_form_range(), but there's a content check on $selecteddate that doesn't exist. I don't see where else it's used in the function either, but I haven't had my third cup of coffee yet this morning. Add error_reporting(-1); to the top of your index page and see what it has to say.

huck Posted March 31, 2014 Author Share Posted March 31, 2014 Inserted the following at the top of both index.php and lib.php. error_reporting(E_ALL | E_STRICT); ini_set("display_errors", 1); No errors pop up when submitting values but page still goes blank. SIDE NOTE: If no values are input, the report shows all mentors and how far they have marked, but as soon as date ranges are set, and submitted, the page goes blank. NOTE: $selecteddate can safely be ignored, since it is not used in index.php or lib.php. After selecting date range and clicking "Get these logs", the page url shows: http://"something.com"/admin/report/mentorprogress/index.php?chooselog=1&fromdate=1394748000&todate=1396216800&logformat=showashtml Then on the page Not Found The requested URL /admin/report/mentorprogress/index.php was not found on this server. Apache Server at "something.com" Port 80 Only thing is that index.php does exist. Full code for both files included. mentor.zip Quote Link to comment https://forums.phpfreaks.com/topic/287408-form-usage-in-php/#findComment-1474512 Share on other sites More sharing options...
ginerjm Posted March 31, 2014 Share Posted March 31, 2014 Do you handle potential query errors by checking the results of the query before trying to use it?

huck Posted April 6, 2014 Author Share Posted April 6, 2014 (edited) Only manually while testing. I have printed the entire date array to screen, and I get valid results as below.
