PHP - What Must Be A Simple Answer.....just Not For Me
Hi again all,
When i add text to my database through a form, it throws an error if i type 'wouldn't', but not if i type a word without an apostrophe. Is there a simple fix for this please peeps? Many Thanks Me@newbie.com.uk+vat Similar Tutorialsi saw this in a php function page he http://php.net/manual/en/function.stristr.php the line is if(stristr($string, 'earth') === FALSE) { specifically this this code <?php $string = 'Hello World!'; if(stristr($string, 'earth') === FALSE) { echo '"earth" not found in string'; } // outputs: "earth" not found in string ?> what is the significance of the '===' in there does it mean something? is there any difference from the '==' or the '=' ? I just finished a page of code that passes all the debug tests except for the very last line on the page. </html>. The page has php and html, java script and some SQL. (see I'm learning and hadn't placed a post until I exhausted my limited resources. The Error Codeis: PHP Parse error: syntax error, unexpected $end in C:\wamp\www\registerform.php on line 292 Here's my concern: I read this error statement as an error()is missing. Please clarify something for me, You start the php code with <?php and end it with ?>. I also understand that the end() will stop all further operation. Correct. When you have a form call itself for data checking, and if the data is correct, send it to the appropriate database table, does one need to place the end() at the end of the php portion of the code? And if so, will it not stop any of the code from being read the first time the page is called? Also since the FORMs action calls for the page to load itself for data verification, how at the end of the checking do I go call another page? here's the page: The page is attached: sorry for posting..i already make it Hi, I have a calculation issue in my php. Below is my code: Code: [Select] $output = ""; $studentId = false; $courseId = false; $moduleId = false; while ($row = mysql_fetch_array($result)){ $moduletotal += $row['Mark']; $modulemark = (int)($moduletotal); //Above here is the calculation for add in the Marks of all the sessions //Below is the code of the display of the query output if($studentId != $row['StudentUsername']) { $studentId = $row['StudentUsername']; $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})"; } if($courseId != $row['CourseId']) { $courseId = $row['CourseId']; $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <br><strong>Year:</strong> {$row['Year']}</p>"; } if($moduleId != $row['ModuleId']) { $moduleId = $row['ModuleId']; $output .= "<p><br><strong>Module:</strong> {$row['ModuleId']} - {$row['ModuleName']} $modulemark</p>"; } $output .= "<p><strong>Session:</strong> {$row['SessionId']} {$row['Mark']}</p>"; } Student: Mayur Patel (u0867587) Course: INFO101 - Bsc Information Communication Technology Year: 3 Module: CHI2550 - Modern Database Applications 72 (72 is the answer to the calculation for the first module but this is incorrect at it should also add the 67 and thus become 139) Session: AAB 72 Session: AAE 67 Module: CHI2513 - Systems Strategy 200 (200 is the answer to the calculation for this module but this is incorrect it should be only 61. But what it has done is that it has added the 72 and 67 from the first module and added it with the 61 in this module) Session: AAD 61 SO WHAT MY QUESTION IS THAT HOW CAN I FIND THE TOTAL OF EACH MODULE MARK WHICH THE VARIABLE $modulemark = (int)($moduletotal); IS TRYING TO DO BY ADDING UP ALL THE SESSIONS MARKS WITHIN EACH MODULE. I HAVE TRIED USING SUM(gr.Mark) in the query and using GROUP BY SessionId, ModuleId, StudentUsername, and CourseId but it ends up not being able to display any records. That is why I want to do the calculation using php rather than SQL. BELOW IS THE QUERY IF YOU WANT TO SEE IT: Code: [Select] $query = " SELECT st.CourseId, c.CourseName, st.Year, st.StudentUsername, st.StudentForename, st.StudentSurname, s.ModuleId, m.ModuleName, m.Credits, s.SessionId, s.SessionWeight, gr.Mark, gr.Grade FROM Course c INNER JOIN Student st ON c.CourseId = st.CourseId JOIN Grade_Report gr ON st.StudentId = gr.StudentId JOIN Session s ON gr.SessionId = s.SessionId JOIN Module m ON s.ModuleId = m.ModuleId WHERE (st.StudentUsername = '".mysql_real_escape_string($studentid)."') ORDER BY c.CourseName, st.StudentUsername, m.ModuleName, s.SessionId "; Hi I made a curl and don't know what to do with the string I got back, I would need the id and the name of each, should I explode, don't know how to do that, here is what I got as answer: Quote string(596) "{"data":[{"name":"Esoterik Forum","category":"Community","id":"180883525283576"},{"name":"Hellsehen und Wahrsagen","category":"Company","id":"177967172214131"},{"name":"Spirituelle Lebensberatung","category":"Website","id":"164411270264299"},{"name":"Esoterik","category":"Website","id":"164524456919432"},{"name":"Kartenlegen und Hellsehen","category":"Company","id":"173933135951523"},{"name":"Exchange","category":"Application","id":"190533567633445"},{"name":"Astrologie","category":"Website","id":"164928140213920"},{"name":"Esoterik Forum","category":"Application","id":"184577371575355"}]}" Hi all, I want to be able to have one file (configuration file i guess) where i set the phone number, address, staff names and positions, etc. and then have them display at different places on various pages. I thought they were inc files, but all i can find is the likes of headers and footers. Any help much appreciated. I just don't know what it's called, if someone can point me in the right direction, thanks. MsKazza When I hit the submit button I would like the answer to appear in the box labled answer. Is that possible? Code: [Select] <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Untitled Document</title> <style type="text/css"> input {position:absolute; left:120px;} p {margin-bottom:-10px;} </style> </head> <body> <form method="post" action="<?php echo $_SERVER['PHP_SELF'];?>"> <p>first number:<input type="text" name="first_number" /></p> <p>second number:<input type="text" name="second_number" /></p> <p>answer:<input type="text" name="answer" /></p> <ul> <li>add: <input type="radio" name="group1" value="add" /></li> <li>subtract: <input type="radio" name="group1" value="subtract" /></li> <li>multiply: <input type="radio" name="group1" value="multiply" /></li> <li>divide: <input type="radio" name="group1" value="divide" /></li> </ul> <p><input type="submit" value="submit" /></p> </form> <?php $answer = $_POST['group1']; $first = $_POST['first_number']; $second = $_POST['second_number']; $ans=0; if ($answer == "add") { $ans = $first + $second; echo $ans; } else if ($answer == "subtract"){ $ans = $first - $second; echo $ans; } else if ($answer == "multiply"){ $ans = $first * $second; echo $ans; } else if ($answer == "divide"){ $ans = $first / $second; echo $ans; } else { echo 'damm...'; } ?> </body> </html> I have a function that creates a dropdown list in a form. The User saves their answer to the mysql table. How do I get their preselected answer back out of the table when they visit the form again? I know how to pull it from mysql and into a variable, but how to modify the below code to display the correct answer stumps me. Here is my dropdown function: Code: [Select] function dropdown($array, $id) { echo '<select name="'.$id.'" id="'.$id.'" class="select"><option value="">Select one...</option>'; foreach($array as $key => $value) { echo '<option value="'.$value.'">'.$value.'</option>'; } echo '</select>'; } Thanks for the help! Hello PHP Freaks forum, I am a beginner in web development and seem to be understanding it very quickly, but there is one thing that is putting this into some halt. I have this code right here, what I want to do is have a "riddle site", where if you answer the riddle correctly, it redirects you to another page (in other words to the next riddle). Object: If correct, give access to next page. If incorrect, stay on page and print "Incorrect". I've tried to start on it, but the way how HTML and PHP don't mix very well, I feel like in the middle of an ocean feeling helpless. <html> <head> <title>PHP Test</title> </head> <body> <p> <font face="Courier New">ZnJ5cyBwYmFnbnZhcnEgaGFxcmVqbmdyZSBvZXJuZ3V2YXQgbmNjbmVuZ2hm</font> </p> CLUE: The base is rotated <br/></body> <form action="index-5.php" method="post"> Answer: <input type="text" name="number" /><br /> </select> <input name="submit" type="submit"> </form> <?php if(isset($_POST['submit'])){ $number = $_POST['number']; if ($number == "scuba"){ echo "CORRECT";} } ?> </html> If possible, can you give me an explanation how to do it and a sample of it as well? Thanks, Gldnbr I'm trying to search the 'ad' column where 'ad' = 1 or 3 I'm having problems doing this. Here is what I currently have, but it is not bringing back 'ad' where ='1' (for obvious reasons) Quote $query = "SELECT * FROM users WHERE ad='3' AND state='$state1'"; Here is what I thought would work, but it displays every listing in my database when I do it this way. Quote $query = "SELECT * FROM users WHERE ad='3' OR ad='1' AND state='$state1'"; Thank you in advance for your answers, google is not being so kind to me right now. I need to make my client's site distinguish among different tabs in the same browser. (See http://www.phpfreaks.com/forums/index.php?topic=357772.0 for background.) I create a tab ID when the user first visits the site in a particular tab, and I'm passing it from page to page as a parameter. This seems to be the only way to do what I need. The tab ID is always passed through POST so that the user won't see it. If it were visible, users could make trouble (or more likely get in trouble) by adding or removing the ID themselves. This is not simple where a page is loaded by a hyperlink. The anchor tag passes parameters via GET, period. The solution I found is to link to a script named post.php, which takes the real link target and the tab ID as parameters, sends the browser a form that passes the tab ID to the real link target via POST, and auto-submits the form via JavaScript. This works, but it requires two round trips to the browser to load a page. It's also a pain to code. Is there a more efficient way to do this... perhaps a way to make the server send the browser a POST response, even though it made a GET request? If it matters, the server is Apache 2.x. Below is my output on the browser: Student: Kevin Smith (u0867587) Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade Year: 3 Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B Session: AAB Session Mark: 72 Session Weight Contribution 20% Session: AAE Session Mark: 67 Session Weight Contribution 40% Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B Session: AAD Session Mark: 61 Session Weight Contribution 50% Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this. Below is the code: Code: [Select] $sessionMark = 0; $sessionWeight = 0; $courseMark = 0; $output = ""; $studentId = false; $courseId = false; $moduleId = false; while ($row = mysql_fetch_array($result)) { $sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']); $sessionWeight += ($row['SessionWeight']); $courseMark = ($sessionMark / $sessionWeight * 100); if($studentId != $row['StudentUsername']) { //Student has changed $studentId = $row['StudentUsername']; $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n"; } if($courseId != $row['CourseId']) { //Course has changed $courseId = $row['CourseId']; $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong> <br><strong>Year:</strong> {$row['Year']}</p>\n"; } if($moduleId != $row['ModuleId']) { //Module has changed if(isset($sessionsAry)) //Don't run function for first record { //Get output for last module and sessions $output .= outputModule($moduleId, $moduleName, $sessionsAry); } //Reset sessions data array and Set values for new module $sessionsAry = array(); $moduleId = $row['ModuleId']; $moduleName = $row['ModuleName']; } //Add session data to array for current module $sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']); } //Get output for last module $output .= outputModule($moduleId, $moduleName, $sessionsAry); //Display the output echo $output; I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72? when in a form, I wish to build a conditional that if the response to a radio button is a value of 2 (female), it will display an input requesting for users maiden name. If not 2 goes to the next input statement. Here is code I was experimenting with: <html> <body> <form action="" name="test" method='POST'> <input type="radio" id="sex" value=1 checked><label>Male</label> <input type="radio" id="sex" value=2><label>Femaleale</label> <?php $result = "value"; if ($result == 2) echo "<input type='int' id='gradYear' size='3' required>"; else echo "Not a female!" ?> <input type="submit" value="GO"> </form> </body> </html> The code passes debug, however, Not a Female is displayed. My question is - Can I do this and if so, what value do I test against id='sex' or value. I tried each one but gave the same results. I realize that $_POST[sex] would be used after the submit button is clicked. But this has me stumped. Thanks for the assis in advance. Hi everyone, I'm trying to select either a class or an id using PHP Simple HTML DOM Parser with absolutely no luck. My example is very simple and seems to comply to the examples given in the manual(http://simplehtmldom.sourceforge.net/manual.htm) but it just wont work, it's driving me up the wall. Here is my example: http://schulnetz.nibis.de/db/schulen/schule.php?schulnr=94468&lschb= I think the HTML is invalid: i cannot parse it. Well i need more examples - probly i have overseen something! If anybody has a working example of Simple-html-dom-parser...i would be happy. The examples on the developersite are not very helpful. your dilbertone Hello, im very green to php and I am having trouble creating a simple log in script. Not sure why this is not working, maybe a mysql_query mistake?

You Are Registered And Can Now Login Warning: Cannot modify header information - headers already sent by (output started at /home/aretheyh/public_html/nealeweb.com/regcheck.php:43) in /home/aretheyh/public_html/nealeweb.com/regcheck.php on line 46 I am trying to write a PHP page that takes an XML file stored on an external server, parses it, and rewrites the data to a new XML file formatted to my liking. The feed is for events and has about 250 events to parse. The problem is that if one event has an empty node, the script will use the same event data for the node used previously. Upon research, I see that empty nodes are parsed as an empty SimpleXMLElement Object. See my code for example: XML Original: Code: [Select] <event_info> <event id="1222209"> <outcome_score><![CDATA[L, 1-0 (OT)]]></outcome_score> <quotes></quotes> <radio>102.9 FM</radio> <sched_opp><![CDATA[Toledo]]></sched_opp> </event> <event id="1222210"> <outcome_score><![CDATA[]]></outcome_score> <quotes></quotes> <radio>107.1 FM</radio> <sched_opp><![CDATA[Ohio]]></sched_opp> </event> </event_info> Output XML (note <outcome_score> on second event): Code: [Select] <event_info> <event id="1222209"> <outcome_score><![CDATA[L, 1-0 (OT)]]></outcome_score> <quotes></quotes> <radio>102.9 FM</radio> <sched_opp><![CDATA[Toledo]]></sched_opp> </event> <event id="1222210"> <outcome_score><![CDATA[L, 1-0 (OT)]]></outcome_score> <quotes></quotes> <radio>107.1 FM</radio> <sched_opp><![CDATA[Ohio]]></sched_opp> </event> </event_info> PHP code: $xml = simplexml_load_file($source); echo "<event_info>"; foreach($xml->event as $event) { echo "<event>"; if($event->outcome_score != '') { echo "<outcome_score><!CDATA[{$event->outcome_score]]></outcome_score>"; } if($event->quotes != '') { echo "<quotes><!CDATA[{$event->quotes]]></quotes>"; } } if($event->radio != '') { echo "<radio><!CDATA[{$event->radio]]></radio>"; } if($event->sched_opp != '') { echo "<sched_opp><!CDATA[{$event->sched_opp]]></sched_opp>"; } echo "</event>"; } echo "</event_info>"; Basically, whenever an event has no outcome score, the most recent outcome score is repeated for all events after. Any help would be greatly appreciated! Thanks! |
