PHP - Move Up And Down And Dealing With Deleted Entries
I have a mysql table like so
ID OrderID Name Image CatalogID 1 1 test pic1.jpg 1 2 2 test2 pic2.jpg 1 3 1 test3 pic3.jpg 2 4 1 test4 pic4.jpg 3 5 1 test5 pic5.jpg 4 6 2 test6 pic6.jpg 4 7 3 test7 pic7.jpg 4 etc etc (1) I want to use up and down buttons so that the OrderID can be modified to reflect the users order preference, how would I code it so it changes all the OrderID values in the table as necessary to produce the correct order using the buttons, the only affected items each time would be the ones in the same CatalogID group. (2) How do I re number the OrderID when an item is deleted so that it moves all the items below it in the same CatalogID group up one value to still reflect the correct order and not skip OrderID values. Similar TutorialsMySQL returns an error in the form of a number, a state, and a message. Without parsing the message you will not be able to determine what column is duplicated.While parsing the error code, I have also notice that, if you have multiple unique fields as duplicates, only the first duplicate encountered will be returned in the message. This is not very helpful to the end user.
Is there any way to parse the returned error code to reflect all duplicate fields, please see sample code below?
$error=array(); $sql = 'INSERT INTO staff(username, email, phone) VALUES (?, ?, ?)'; $stmt = $conn->stmt_init(); $stmt = $conn->prepare($sql); // bind parameters and insert the details into the database $stmt->bind_param('sss', $username, $email, $phone); $stmt->execute(); if ($stmt->errno == 1062) { $errors[] = "One of the fields is already in use."; } I have this code to update mysql db. It deletes and updates everything in the row except for the date. The date remains the same. In my db i have it under "prices" and it is named "date". Here is the code I am using. Code: [Select] if($user_id !="" && $name !="" && $update=="yes"){ mysql_query("DELETE FROM prices WHERE id='".$_POST['id']."'"); $resultado = "You successfully updated this posting!<br>Thank you for participating."; $date=getdate(); $insert=mysql_query("INSERT INTO prices VALUES ('', '$user_id', '$name', '$bus_type', '$street', '$city', '$state', '$zip_code', '$brand', '$quantity', '$price1', '$price2', now())"); } Hi I have deleted quite lot data from mysql database however, php still shows that page but blank ie page.php?id=186 - this id and all assosiated fields with this id has been removed from mysql but id still showing on the net and google cached all of them ( 600 pages) . page.php is still in use but I was wondering if there is any way not to show these blank pages/ids from mysql db and more importantly how can I remove these blank pages from google? Thanks for your help. How can I recover deleted iphone contacts?
I'm pulling my hair out here... Here's my problem. I'm about halfway done with my site (It's a site to sell stuff and I'm working on the shopping cart) when I noticed a big problem. I've got session cookies working in every browser (FF, chrome, safari) except Internet Explorer. For some reason IE likes to delete my session cookies so there's nothing there after I click 'view shopping cart'. I've verified that the session is set but then it gets deleted. Now I am using IFrames and I searched for possible causes and tried changing headers, making sure there's no underscores, etc... No joy The problem is that getting the problem to show up would require a lot of copying code onto this page since it's like 4 or 5 pages to get something into the cart and then view the cart itself. What do you folks recommend? Should I just link to the site itself? I have approximately 2,300 videos embedded on my site, and I am constantly adding more. The videos are hosted by YouTube. When a video is deleted from YouTube, it becomes unavailable on my site. Each video's ID is in my MySQL database. A video ID looks like this: ZFOuxAx-dkc I need a script that will do the following: select the IDs from my database check if the videos are still available on YouTube create a list of the videos that are unavailable. If possible, it would be great if the script could also tell me if any of the videos have been blocked in certain countries. The script has to be fully commented so that I can understand it. I want to run the script manually every few days. I don't want to have to change my database tables. I've been told that you can use YouTube's API or YouTube's oEmbed interface. I've also been told that, because there are so many videos, you will have to use cURL multi handles. If interested in this project, please PM me your price. This is an urgent project. I have placed ads elsewhere. So if I have this code (while working on my local machine )... Code: [Select] for ($i=1; $i<=15; $i++) { if ($timelimit == $i) { ${"time".$i}="selected='selected'"; } } <select name="timelimit"> <option value="1" <?php echo $time1;?>>1</option> <option value="2" <?php echo $time2;?>>2</option> <option value="3" <?php echo $time3;?>>3</option> <option value="4" <?php echo $time4;?>>4</option> <option value="5" <?php echo $time5;?>>5</option> <option value="6" <?php echo $time6;?>>6</option> <option value="7" <?php echo $time7;?>>7</option> <option value="8" <?php echo $time8;?>>8</option> <option value="9" <?php echo $time9;?>>9</option> <option value="10" <?php echo $time10;?>>10</option> <option value="11" <?php echo $time11;?>>11</option> <option value="12" <?php echo $time12;?>>12</option> <option value="13" <?php echo $time13;?>>13</option> <option value="14" <?php echo $time14;?>>14</option> <option value="15" <?php echo $time15;?>>15</option> </select> When I view the select menu in the browser, all but one of the options says "Notice: Undefined variable: time1 in C:\wamp\www\yyyyyy\create.php on line 112". It doesn't say this if I publish everything to the internet. So the question is, should I put code in to eliminate those Notices, or does it not matter. In other words, if I add this snippet below to declare all the other variables, it eliminates all the Notices. But is this necessary/good practice to do?.. Code: [Select] for ($i=1; $i<=15; $i++) { ${"time".$i}=""; } <?php if ($beyondportal % 26 == 0 || $beyondportal == 0){ ?> MY CONTENT <?php } ; ?> This code compares my variable $beyondportal and if it is a multiple of 26 counting up from 0, it prints my content. This is great but sometimes the number comes up a negative that is a multiple counting down from 0 like -26, -52, etc.. if I could do the opposite of a modulus I would think it would work but I'm not sure how to in php. any suggestions? I am using file_get_contents to get file off the internet for further processing but somtetimes there is error fetching that file off the web in which case it would be nice to try to reload it again but I am not sure what would be best way to do it? How can I jump back on error? I guess there would have to be some jump to label condition, but how do I implement this? This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=313673.0 Hi I found a tutorial on dealing with databases he http://www.phpfreaks.com/tutorial/php-basic-database-handling It's great, except that I need it to do more than just a name; I need first, last, dob and email. I have it figured out how to order, insert and delete, but can someone help me figure out how to do the updating? The tutorial creates an array called cname and loops through it to do the update, but when I add more fields, it only holds the last fileds (emails in this case) I just need to be able to update all the fields for each user instead of just the name. Sounds easy but I've gotten nowhere Everything I have tried is posted below. Any help?

'</td><td>'. $row["Label"]. '</td><td>'. $row["Value"]. '</td>'; if ($i == 1): echo '<td>'. $row["SKU"]. '</td><td>'. $row["Value"]. '</td>'; else: echo '<td>'. $row["Value"]. '</td>'; endif; #echo '<td>'. $row["Value"]. '</td>'; endforeach; echo '</tr>'; endforeach; ?> And looks like: Product code System Pack Quantity XT1CWH System 1 1 x 3m XT2CWH System 2 1 x 3m XT3CWH System 3 1 x 3m
This works perfectly fine. However, some products share the same SKU and therefore it causes an issue, like the below: Product code System Pack Quantity XT1CLWH System 1 8 x 3m System 2 8 x 3m System 3 8 x 3m Is there a way I can avoid this, so if perhaps creates the new row but shows the same SKU code? Many thanks I am using Guzzle as a HTTP client, and the following script results in the following error: $response = $this->httpClient->request('GET', "http://$this->host:$this->port/query", ['query' => $data]); $body = $response->getBody(); $rs=json_decode($body, true); Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 136956008 bytes) in /var/www/vendor/guzzlehttp/psr7/src/Stream.php on line 80 What are the work arounds? Instead of trying to convert it into an array all at once, how can I do so in pieces? I know the expected format so it seems I will need to read just the appropriate amount of bytes and then decode parts at a time. Seems like a pain. Are there any classes designed to do so, or can any of the following Guzzle built in methods be used?

Hi I am new to PHP / mySQL although not to programming and am trying to work out how to deal with the following situation: I have a form for a user to add a book to a database, along with the genres that the book belongs to. Each book can have a number of genres . There are 3 tables, books, genres and bg_xref in the following formats table: books fields: id, title, author, date published table: genres fields: id, genre table: bg_xref fields: id, book_id, genre_id I am now trying to build the form that allows the user to update an existing entry for a book. the genres are selectable from a multi-selection list which I am populating from all the possible values in the genres table. Currently I have the following database selections: mysql_select_db($database_conn, $conn1); $query_rs_getBooks = "SELECT books.id, books.title, books.author, bg_xref.genre_id FROM books LEFT JOIN bg_xref ON books.id = bg_xref.book_id"; $rs_getBooks = mysql_query($query_rs_getBooks, $conn1) or die(mysql_error()); $row_rs_getBooks = mysql_fetch_assoc($rs_getBooks); mysql_select_db($database_conn, $conn1); $query_rs_getGenre = "SELECT * FROM book_genres ORDER BY genre ASC"; $rs_getGenre = mysql_query($query_rs_getGenre, $conn1) or die(mysql_error()); $row_rs_getGenre = mysql_fetch_assoc($rs_getGenre); I have then created a form that the user uses to update the book, but am trying to work out how to prepopulate the selection list based on teh results of the join e.g. <form method="POST" action="<?php echo $editFormAction; ?>" name="update_book"> <fieldset class="full"> <legend>Enter book details below</legend> <table> <tr><td>Title: </td><td><input type="text" size="50" value="<?php echo htmlentities($row_rs_getBooks['title'], ENT_COMPAT, 'iso-8859-1'); ?>" name="title"></td></tr> <tr><td>Author: </td><td><input type="text" size="30" value="<?php echo htmlentities($row_rs_getBooks['author'], ENT_COMPAT, 'iso-8859-1'); ?>" name="author_surname"></td></tr> <tr><td>Genre(s)</td><td><select name="genre" multiple size="4"> <?php do { ?> <?php if (($row_rs_getBooks['genre_id']) != $row_rs_getGenre['id']) { ?> <option value="<?php echo $row_rs_getGenre['id']?>"><?php echo $row_rs_getGenre['description']?></option> <?php } else { ?> <option value="<?php echo $row_rs_getGenre['id']?>" selected><?php echo $row_rs_getGenre['description']?></option> <?php } } while ($row_rs_getGenre = mysql_fetch_assoc($rs_getGenre)); $rows = mysql_num_rows($rs_getGenre); if($rows > 0) { mysql_data_seek($rs_getGenre, 0); $row_rs_getGenre = mysql_fetch_assoc($rs_getGenre); } ?> </select></td></tr> </table> </fieldset> <input type="hidden" name="id" value="<?php echo $row_rs_getBooks['id']; ?>"> <input type="submit" value="Update book details"> <input type="hidden" name="MM_update" value="update_book"> </form> Book id = 1 is classified against genres 1 and 5, so my SQL query returns 2 rows: book.id = 1 + bg_xref.genre_id = 1 book.id = 1 + bg_xref.genre_id = 5 At the moment the form is generated for the first row of the results set with <tr><td>Genre(s)</td><td><select name="genre" multiple size="4"> <option value="5">Humour</option> <option value="4">Non Fiction</option> <option value="2">Novel</option> <option value="3">Picture Books</option> <option value="1" selected>Poetry</option> with a second entry in the results set for book 1 and genre 5. What I need to end up with is a second occurence of book 1 with both genres 1 and 5 set in the form. Thanks Stuart I'm dealing with data that WordPress creates for Users when they register and subscribe, and to use it for other purposes, I have to wrap my head around serialized data. It's not sinking in well. The below code works well for what I wanted at the time. It takes into consideration where the Subscriber lives (divided up into five areas) and counts how many I have. That is noted by wp_s2member_custom_fields and ANY s2member_level. There are three levels, and I need to actually note how many there are at each Member level. There is another line of data for each user_id meta_key = wp_capabilities meta_value = a:1:{s:15:"s2member_level2";s:1:"1";} Code: [Select] $custom = 'SELECT * FROM wp_usermeta WHERE meta_key = "wp_s2member_custom_fields" AND user_id IN (SELECT user_id FROM wp_usermeta WHERE meta_value LIKE "%s2member_level%")'; $c_results = mysql_query($custom); $region = array(); while($line = mysql_fetch_assoc($c_results)) { $meta_value = unserialize($line['meta_value']); $region[$meta_value['county']]++; }; foreach ($region as $key => $value) { echo "Region $key: $value members<br>"; } Using MySQL and PHP. I have two tables mobiles and brands. mobiles has { mobileID |brandID | price| BrandName| MobileName} brands has { brandID | BrandName } In admin panel admin is able to delete both the table indivdiually but I want that if brand is deleted all the related mobiles should also be deleted How is this possible? Below is the part of my code that creates the html table. How do I add pagination every 30 entries? $db = mysql_connect("localhost","trend_learnu","asdfasdf"); mysql_select_db("trend_learningdb",$db); $result = mysql_query("SELECT * FROM Peoples ORDER BY number ASC"); $table = '<table width="608" border="0" align="center" cellpadding="10" cellspacing="0"> <tr> <td style="color:#fff;" width="207" bgcolor="#425d74"><strong>Firstname</strong></td> <td style="color:#fff;" width="204" bgcolor="#425d74"><strong>Lastname</strong></td> <td style="color:#fff;" width="197" bgcolor="#425d74"><strong>Date</strong></td> <td style="color:#fff;" width="197" bgcolor="#425d74"><strong>Weight</strong></td> </tr>'; while($row=mysql_fetch_array($result)) { $firstname = $row['Firstname']; $lastname = $row['Lastname']; $weight = $row['Weight']; $date = $row['Date']; $table.= '<tr>'; $table.= '<td bgcolor="#e8f4ff">'.$firstname.'</td>'; $table.= '<td bgcolor="#e8f4ff">'.$lastname.'</td>'; $table.= '<td bgcolor="#e8f4ff">'.$date.'</td>'; $table.= '<td bgcolor="#e0ffe6"><strong>'.$weight.'</strong></td>'; $table.= '</tr>'; } $table .= '</table>'; echo $table; mysql_close($con) the problem is that when I add an item to be displayed in the blog, shows three instead, which two are empty.
