PHP - Url Not Being Generated
On a website currently under development the URL does not change when navigating around on the page. It always displays the root URL.
This is the script that should generate the links: $URLvars=substr($_SERVER["PHP_SELF"], strrpos($_SERVER["PHP_SELF"],"/")+1); $vatLink=$URLvars; $thisPageURL=$_SERVER["PHP_SELF"]; if(strpos($thisPageURL, "secure/locktech/")!==false)$thisPageURL=substr($_SERVER["PHP_SELF"], 16); $prodLink="http://www.lock-tech.co.uk".$thisPageURL; It used to. However, the server has changed and it does not any more. Is it maybe because the 2 paths (http://www.lock-tech.co.uk and secure/locktech/) must be changed according to the new server? Does anyone know what exactly do these paths stand for? I understand that one of them is the root path but what does the path in the line Code: [Select] if(strpos($thisPageURL, "secure/locktech/")!==false)$thisPageURL=substr($_SERVER["PHP_SELF"], 16); stand for? Similar TutorialsI'm trying to generate RSS by using PHP and MySQL but I keep getting an error message that I don't know how to solve.

Thanks I have something like this on one of my pages: $name = 'Bob'; Code: [Select] if ((isset($_POST['name'])) || ($_POST['name'] == '')) { $name = $_POST['name']; //update database } echo '<form action='' method='POST'>'; echo '<table><tr><td width="125">Name: </td><td><input type="text" name="signature" style="width: 270px;" value="' . $name . '" /></td></tr></table>'; echo '</form>'; Here's the problem: Initially, because the form data has not been sent the input box says: 'Bob'. If I remove the name Bob from the input box by manually clicking in it and deleting the name, and I submit the form, it keeps showing 'Bob', whereas I would like it to be empty. What am I doing wrong? I'm wanting to make a sitemap for my website but as it's quite big there are a lot of url's I need to include. I was wondering if anyone know's of a way this can be done using PHP. e.g. using PHP to generate a list of URL's. I had a think myself but wasn't sure how to do it. Thanks for any help. I currently have a query that compiles a League Standings Table (the full code is below) and generate the ranking with Code: [Select] @rownum := @rownum+1 AS rank This works fine for the main standings page but I want to use the row numbers elsewhere. Each team has it's own page which uses 'team.team_id' as its 'recordID'. On these pages I would like to show that particular teams ranking in the standings. The two options I see would be to run the query filtering by 'team.team_id' but that would only return the one record so ranking would always be '1' or run the whole query and then somehow find which ranking relates to 'team.team_id' (something that may be possible with VIEWS but the database is running on MySQL4) but I cannot figure out how to get around this. For example, if the standings were Rank Team 1 Rovers 2 United 3 City 4 Rangers 5 Town 6 Athletic 7 Wanderers 8 Hotspur On the 'Rangers' page I would want it to show 'RANKING: 4' and on the 'Athletic' page it would show 'RANKING: 6'. On top of this I would want to show a small version of the rankings with one team above and one team below (it would actually be two teams but I will keep it simple until I understand it!) so one again given the two examples above I would get RANGERS PAGE Rank Team 3 City 4 Rangers 5 Town ATHLETIC PAGE Rank Team 5 Town 6 Athletic 7 Wanderers The query is $i = 1; $ht = "g.home_team = t.team_id"; $at = "g.away_team = t.team_id"; $hw = "g.home_goals > g.away_goals"; $aw = "g.home_goals < g.away_goals"; $d = "g.home_goals = g.away_goals"; $hg ="g.home_goals"; $ag ="g.away_goals"; $table = mysql_query("SELECT t.team_name as Tm, @rownum := @rownum+1 AS rank , (sum(CASE WHEN (".$ht."

Can someone explain why @rownum := @rownum+1 AS rank causes $i to increment by one? I found the code while searching and do not understand why $i is necessary unless it is a reserved reference. The way the code looks, I should be able to output the ranking using 'rank' but that does not work. I have no problem with how it does things, it would just be nice to understand! My PHP code is generating XML with a blank first line before the <?xml version="1.0" ?> see http://urbanbees.co.uk/maps/phpsqlajax_genxml3.php I have been told this is the reason why my map is not showing the markers in chrome and FF but it is OK in IE8. see http://urbanbees.co.uk/maps/map_of_hive_locations_update.htm You'll either see markers or not depending on your broswer. How do I change the code to not generate this first blank line. Here is the php code. <?php require("phpsqlajax_dbinfo.php"); // Start XML file, create parent node $dom = new DOMDocument("1.0"); $node = $dom->createElement("markers"); $parnode = $dom->appendChild($node); // Opens a connection to a MySQL server $connection=mysql_connect (localhost, $username, $password); if (!$connection) { die('Not connected : ' . mysql_error());} // Set the active MySQL database $db_selected = mysql_select_db($database, $connection); if (!$db_selected) { die ('Can\'t use db : ' . mysql_error()); } // Select all the rows in the markers table $query = "SELECT * FROM markers WHERE 1"; $result = mysql_query($query); if (!$result) { die('Invalid query: ' . mysql_error()); } header("Content-type: text/xml"); // Iterate through the rows, adding XML nodes for each while ($row = @mysql_fetch_assoc($result)){ // ADD TO XML DOCUMENT NODE $node = $dom->createElement("marker"); $newnode = $parnode->appendChild($node); $newnode->setAttribute("name",$row['name']); $newnode->setAttribute("address", $row['address']); $newnode->setAttribute("lat", $row['lat']); $newnode->setAttribute("lng", $row['lng']); $newnode->setAttribute("type", $row['type']); } echo $dom->saveXML(); ?> I'm not sure of the appropriate subject line for this feature, but hopefully I'm close. I'll try to describe what I'm trying to do. The most common place you see this is on web based file uploads so I'll use it as my example. Let's say I want to allow my user to upload files so there is a text box where they enter the file name. The user is allowed to upload as many files as he wants with 1 push of the submit button. Upon the loading of the form, there will be 5 textboxes for file upload, but if the user wants to upload more than 5 files, there is a link that is clicked and I think via ajax or javascript another textbox will be added. The user can do this for as many files he wants to upload. This is what it looks like to the user, but then when the form is submitted how are these variables referenced? So how is this setup in the main form and how are the variables referenced after form submission? If anyone can point me to a good web tutorial on this type of thing I would appreciate it. Thanks Carl Hi, I have a question here. Currently my $tutor_id is auto incremental in my SQL, and it is in running numbers. However I will like to add a 'T' in front of the id. Example: Currently, our id number is 1 2 3 4 etc. Would like to achieve T1 T2 T3 T4 etc. How do I do it? Below is my code as well. Please kindly advise. Thanks /**INSERT into tutor_id table to create a new id for new tutors**/ $query = "INSERT INTO tutor_id (id) " . "VALUES ('$id')"; $results = mysqli_query($dbc, $query) or die(mysqli_error()); $tutor_id = mysqli_insert_id($dbc); /**INSERT into tutor table**/ $query1 = "INSERT INTO tutor (tutor_id, email) " . "VALUES ('$tutor_id', '$email')"; $results1 = mysqli_query($dbc, $query1) or die(mysqli_error()); Hi Mates, I want to know how to create auto generated pages in submit button with the existing templates...Wordpress users may easily understand what actually i mean...i am using the code that is creating a page but not getting the desired page name and giving a blank page that is without any formatting... Code: [Select] <?php $content = <<<EOL <head> </head> <body> New page EOL; include ('config.php'); mysql_select_db("$db_name"); $result = mysql_query("SELECT * FROM text ORDER BY ID") or die(mysql_error()); while($row = mysql_fetch_array( $result )) { echo $row['title']; echo "<br />"; } $content .= <<<EOL </body> </html> EOL; $file = '$result' . '.php'; $open = fopen($file, "w"); fwrite($open, $content); fclose($open); ?> Hi, I am trying to get some charecters to display properly in emails that are sent via a form on my site. The finnish characters ä and ö come out as squares when viewed in Outlook. I have tried various encoding types such as UTF-8 and Western European (dreamweaver), both as the script encoding and as the encoding in the mail() function. $body = 'Sähköposti:' ; mail($salesEmail, "Call Back Request", $body, "MIME-Version: 1.0\r\nContent-type: text/html; charset=utf-8\r\nFrom: $salesEmail") ; = 'S�hk�posti:' or just squares in Outlook. I have also tried hard coding them as ä and ö and the symbol literals to no effect. Does anyone know what is causing this? Ok, so I currently have this http://pastebin.com/cCgyavs0 snippet that generates links to the previous, next and last page based on the current page (GET variable) or the total item count in the MySQL DB to then use forms as links by inserting the URLs into the action attribute. I did this cause I don't wanna use images as links, btw :P It kinda works - I get links like: shop.php?page=1 shop.php?page=12 shop.php?page=14 shop.php?page=225 When I'm on page 13 of 225 for example. Though when I click one of the buttons, I always get redirected to "shop.php?". :/ Hey all, I have a relationship where a zone has many posts and a category has many zones but a zone can also have many categories. The zones are basically parts of a page, such as the main area and sidepanel stored in database as records with name fields such as 'panel' and 'main'. There's a serious flaw right now and I would like to know the best solution to address it. Right now I access the posts of a zone of a category like this: Code: [Select] $category->zone->get()->post->get(); The above ends up displaying all the posts in the database for any given category because when category is selected, it searches for the associating zones, and then selects all posts related to those zones, which is wrong. i want to select all posts of the zones associated with that particular category. Current database: Code: [Select] posts id zone_id zones id name categories_zones id zone_id category_id categories id What should I do? Add a category_id column to the posts table and relate the post directly to the category as well as directly to the zones table so the post table would have two foreign keys: category_id and zone_id Would this be the most effective thing to do given my requirements? Thanks for response. Hi. I have a rating site where users fill in a name of what they are rating, comments about it and a rating and submit it to my database. I then have another page which shows all of these entries but only the name and overall rating using php. What I want is for users to click on the name and it take them to a separate page which displays all the comments and ratings for that item. As users can add items to rate I cant set up a page for each manually so was wondering how to do it dynamically. Everything i throw into google leads me in the wrong direction though. If someone could point me to a good tutorial or give me an idea about what to search id be very grateful. Cheers. Hello I've spent the last few hours writing a small php file that creates a signature for Steam (a gaming platform) and saves it as a png. It basically just pulls the neceassary info and images from the user's Steam XML stream and uses GD to arrange it nicely. A link to an example is here. Now, the trouble I have is that it saves the image as a .php file (it can be downloaded as a png but not linked to as one, images.php.png doesn't exist). I can navigate to the webpage and save as a png but for obvious reasons can't link to it as an image (making the forum signature part kind of hard to pull off). Is there any easy way (I'm unspeakably bad with php) that I can save the php graphic as a PNG to an external page (for example /sig_name.png or /images.php?id=name.png)? Thanks for any help Hi guys, Im making an event booking/reservation site, I have 5 tables (Malls, Events, Booking, Reservation and Users) which are all connected and doing fine. I created a function which is this... function select_all_events_by_mall_id($mall_id) { echo "<table id='event_table'>"; echo "<th>Event Name</th>"; echo "<th>Event Location</th>"; echo "<th>Number of Cars</th>"; echo "<th>Description</th>"; echo "<th>Booked</th>"; echo "<th>Reserved</th>"; echo "<th>Reserved Until</th>"; echo "<th>Vacant</th>"; $events_set = select_all_events($mall_id); while($events = mysql_fetch_array($events_set)) { echo "<tr>"; echo "<td>" . $events['event_name'] . "</td>"; echo "<td>" . $events['event_location'] . "</td>"; echo "<td>" . $events['number_of_cars'] . "</td>"; echo "<td>" . $events['description'] . "</td>"; // Booked echo "<td>"; $booked_set = select_all_booking($events['id']); while($booked = mysql_fetch_array($booked_set)) { $user_set = select_all_user_booked($booked['users_id']); while($user = mysql_fetch_array($user_set)) { echo $user['company'] . ", " . $user['branch'] . "<br />"; } } echo "</td>"; // Reserved echo "<td>"; echo "<ol>"; $reserved_set = select_all_reservation($events['id']); while($reserved = mysql_fetch_array($reserved_set)) { if(empty($reserved['events_id'])) { echo "No Reservation's "; } else { $reserved_user = select_all_user_reserved($reserved['users_id']); while($user_set = mysql_fetch_array($reserved_user)) { echo "<li>" . $user_set['brand'] .

"</li>"; } } } echo "</ol>"; echo "</td>"; //Vacant echo "<td>"; $vacant_set = select_all_booking($events['id']); $booking_count = mysql_num_rows($vacant_set); $reserved_count = mysql_num_rows($reserved_set); $total_count = $booking_count + $reserved_count; $vacant = $events['number_of_cars'] - $total_count; if($vacant < 0) { echo "This Event is fully booked"; } else { echo $vacant; } echo"</td>"; echo "</tr>"; } echo "</table>"; } The function starts by receiving an id from picking a mall name from a select tag. It works fine, it outputs the data on the page like i want it to, but my problem is that i need a way to add a submit or any button to each generated row that will, when clicked will insert the event id and user id (who clicked it) to my booking/reservation table as a new row. I tried adding a form inside my function and saving the event id every loop but when i click the submit button i think it doesn't work (or i made a mistake).. Sorry if my coding sucks, I'm kinda new in php. Sorry if its kinda confusing my head is spinning right now from thinking this stuff the whole day.. Thanks in advance for any comments and ideas. I am putting title in my URL whenever a new auto generated page is generates, so if i use single word tile then it is fine but when there is more that two words in the title it shows space in every word and therefor in title too. how can i add this hyphen or any other special char to my URL so it would look like? i.e. If i use title to MY FIRST WEB PAGE.php, what should i do so i can make it like MY-FIRST-WEB-PAGE.php hey all so I have this bit down: Code: [Select] $query="SELECT `2010 Region Code` AS codes FROM locations"; $results = mysql_query($query); $options=""; $options = "<select location='codes'>"; while($nt=mysql_fetch_assoc($results)) { $thing=$nt["codes"]; $options.="\r\n<option value ='{$nt['codes']}'> {$nt['codes']}</option>"; } $options .="\r\n</select>"; echo $options; what I'm trying to do is grab the selection from the drop down and display it as a table (the sql query would be extended should we manage to figure this one out I've tried Code: [Select] echo"<form name='LOCATIONS' action='".$_SERVER['PHP_SELF']."' target='iframe' method='post'>"; any ideas? I have a full-text RSS component for Joomla that I was trying to modify. I wanted to be able to truncate the article to a given number of words and place a link at the end for the rest of the article. I need help figuring out how to add a link to the end of the source article. Added this script to the post.php file. It sort of works but the "$ending" tag doesn't seem to function since there is no "..." appended to the end of articles posted, when I tested it. public function truncate($text, $length = 200, $ending = '...', $exact = true, $considerHtml = false) { if ($considerHtml) { // if the plain text is shorter than the maximum length, return the whole text if (str_word_count(preg_replace('/<.*?>/', '', $text)) <= $length) { return $text; } // splits all html-tags to scanable lines preg_match_all('/(<.+?>)?([^<>]*)/s', $text, $lines, PREG_SET_ORDER); $total_length = str_word_count($ending); $open_tags = array(); $truncate = ''; foreach ($lines as $line_matchings) { // if there is any html-tag in this line, handle it and add it (uncounted) to the output if (!empty($line_matchings[1])) { // if it's an "empty element" with or without xhtml-conform closing slash (f.e. <br/>) if (preg_match('/^<(\s*.+?\/\s*|\s*(img|br|input|hr|area|base|basefont|col|frame|isindex|link|meta|param)(\s.+?)?)>$/is', $line_matchings[1])) { // do nothing // if tag is a closing tag (f.e. </b>) } else if (preg_match('/^<\s*\/([^\s]+?)\s*>$/s', $line_matchings[1], $tag_matchings)) { // delete tag from $open_tags list $pos = array_search($tag_matchings[1], $open_tags); if ($pos !== false) { unset($open_tags[$pos]); } // if tag is an opening tag (f.e. <b>) } else if (preg_match('/^<\s*([^\s>!]+).*?>$/s', $line_matchings[1], $tag_matchings)) { // add tag to the beginning of $open_tags list array_unshift($open_tags, strtolower($tag_matchings[1])); } // add html-tag to $truncate'd text $truncate .= $line_matchings[1]; } // calculate the length of the plain text part of the line; handle entities as one character $content_length = str_word_count(preg_replace('/&[0-9a-z]{2,8};|&#[0-9]{1,7};|[0-9a-f]{1,6};/i', ' ', $line_matchings[2])); if ($total_length+$content_length> $length) { // the number of characters which are left $left = $length - $total_length; $entities_length = 0; // search for html entities if (preg_match_all('/&[0-9a-z]{2,8};|&#[0-9]{1,7};|[0-9a-f]{1,6};/i', $line_matchings[2], $entities, PREG_OFFSET_CAPTURE)) { // calculate the real length of all entities in the legal range foreach ($entities[0] as $entity) { if ($entity[1]+1-$entities_length <= $left) { $left--; $entities_length += str_word_count($entity[0]); } else { // no more characters left break; } } } $truncate .= substr($line_matchings[2], 0, $left+$entities_length); // maximum lenght is reached, so get off the loop break; } else { $truncate .= $line_matchings[2]; $total_length += $content_length; } // if the maximum length is reached, get off the loop if($total_length>= $length) { break; } } } else { if (str_word_count($text) <= $length) { return $text; } else { $truncate = substr($text, 0, $length - str_word_count($ending)); } } // if the words shouldn't be cut in the middle... if (!$exact) { // ...search the last occurance of a space... $spacepos = strrpos($truncate, ' '); if (isset($spacepos)) { // ...and cut the text in this position $truncate = substr($truncate, 0, $spacepos); } } // add the defined ending to the text $truncate .= $ending; if($considerHtml) { // close all unclosed html-tags foreach ($open_tags as $tag) { $truncate .= '</' . $tag . '>'; } } return $truncate; } I have attached the whole file as well if you want to see the rest. This part of the script has the function that originally automatically added the link to the source article: if($link_original==1){ if(strlen($ret->fullText)) $ret->fullText.="<p><a href='". $item->link."' target='_blank'>".$text_link_original."</a></p>"; else $ret->introText.="<p><a href='". $item->link."' target='_blank'>".$text_link_original."</a></p>"; } The problem is that it gets truncated with the rest of the article now. Hi everyone, first of all let me thank you for this wonderful forum I come back here always when i need help... i'm trying to learn so soon i hope, i'll be helping others... I have a question for now, i have a code which goes like this: Code: [Select] <? $b = time (); $date1 =date( "Y-m-d;h:i:s" , mktime(date("h")+6, date("i"), date("s"), date("m") , date("d"), date("Y"))); $str_time = "&receivedtimestamp="; $str_msg = "&msg=bkt"; $str_from = "from="; ?> <a href="http://testext.i-movo.com/api/receivesms.aspx?<?echo $str_from;?><?=$getuser[0]['phone'];?><?echo $str_time;?><?echo $date1;?><?echo $str_msg;?>">Get a Cupon</a> What i need is that when the URL is generated, one of those variables to be hidden, for example the $str_from to be in the link but not visible... I must tell you that the link on the Get Cupon goes to an external link so i don't know if i can do it with .httpaccess as i've heard... Can anyone tell me, how the temporary file names (name of the file which is created in the 'tmp' dir ) generated by PHP when the files are uploaded ? Are there any algorithms used ? Hey all, I'm almost too embarrased to post this as I'm sure it is very simple - but for the life of me I can't get this to work. I am a complete newbie to PHP so please bear with me.. What I'm trying to do is to write a program that will go on to calculate a user's Body Mass Index (BMI) based on user inputted data of height and weight. However, I want to be able to accept heights and weights in a number of different units for maximum ease of use. I am trying to write some PHP code that will handle this , the main goal is to convert everything into 'cm' and 'kg' before going on and doing the simple BMI calculation later on. However I am stuck at this point: I have a text field for users to input their weight into. This is immediately followed by two radio buttons for the user to select which units they are inputting their weight in (kilograms or pounds). A third option to input their weight is given after this for those wishing to input their weight in 'stones and pounds'. My problem is as follows: I can't get my code to recognise which radio button (either 'kg' or 'lbs') has been pressed. What should happen is that my code can tell something has been inputted in the text box AND which of the radio buttons has been selected. From this it does one of the two; for the kilogram option it leaves the value as it is, but if the weight has been inputted in pounds (and the 'lbs' radio button selected) then I want the code to convert this into kilos by multiplying by 0.4535. Here is what I have so far (sorry its a bit messy - like i say I am a newbie): <?php //convert.php $ft = $cm = $inches = $weight = $stones =$pounds = $kilos = $units = ""; if(isset($_POST['cm'])) $cm = sanitizeString($_POST['cm']); if(isset($_POST['ft'])) $ft = sanitizeString($_POST['ft']); if(isset($_POST['inches'])) $inches = sanitizeString($_POST['inches']); if(isset($_POST['weight'])) $weight = sanitizeString($_POST['weight']); if(isset($_POST['stones'])) $stones = sanitizeString($_POST['stones']); if(isset($_POST['pounds'])) $pounds = sanitizeString($_POST['pounds']); if(isset($_POST['kilos'])) $kilos = sanitizeString($_POST['kilos']); if(isset($_POST['units'])) $units = sanitizeString($_POST['units']); if ($ft != '') { $height = intval(($ft * 30.48) + ($inches * 2.54)); $out = "you are $height cm tall"; } elseif($cm != '') { $height = intval($cm); $out = "you are $height cm tall"; } else $out = ""; if ($stones != '') { $kilos = intval((($stones * 14) + $pounds) * 0.45359237); $out2 = "you weigh $kilos Kg"; } elseif($weight != '' AND $units = "kg") { $kilos = $weight; $out2 = "you weigh $kilos Kg"; } elseif($weight != '' AND $units = "lbs") { $kilos = ($weight * 0.45359237); $out2 = "you weigh $kilos Kg"; } else $out2 = ""; echo <<<_END <html><head><title>Height & Weight Converter</title> </head><body><pre> Please enter your details below <b>$out$out2</b> <form method="post" action="convert.php"> Height: <input type="text" name="cm" size="3"> cm OR <input type="text" name="ft" size="1">ft <input type="text" name="inches" size="2">inches Weight: <input type="text" name="weight" size="4" /> Kg<input type="radio" name="units" value="kg" /> lbs<input type="radio" name="units" value="lbs" /> OR <input type="text" name="stones" size="2">stone <input type="text" name="pounds" size="2">pounds <input type="submit" value="Submit" /> </form></pre></body></html> _END; function sanitizeString($var) { $var = stripslashes($var); $var = htmlentities($var); $var = strip_tags($var); return $var; } ?> |
