Dynamically Sorting MysQL Table Rows With Links?
I've just created a simple CMS but there's a certain functionality I want but dont know where to begin. Ive created a page that lists the records from a table in my database. That works fine. But what I now want to be able to do is have 2 links next to each record that moves the desired record up or down in the listing. I assume that this is a case of swapping the record id numbers so the order of the database information is changed? Does anyone have any knowledge of this or could point me in the right direction to help me out?

How Do I Delete Selected Rows From MySQL Table?
I am trying to figure out how to delete selected rows from a MySQL database table. The web site that I am working on has a page that will extract rows, using the "SELECT * FROM .. etc." statement from a database and output them in a table - like the one below (bottom part). I've got that part figured out.

Table Sorting Logic
I have a table with 4 columns. I have each column header acting as an asc/des sort on that column. I also have 4 filters that a user can apply to the table. What is supposed to happen.... If a user clicks on a column header twice in a row ( or 100 times in a row) the table will toggle back and forth between an asc/des sort on that column. If a user clicks on a "new" column header, the sort will reset to the initial asc/des value assigned to that column instead of just toggling from the current setting. If a user clicks on a filter, the results will be displayed with the "current" sorting method. What is actually happening.... Everything seems to be working fine except when a user clicks on the same filter link more than once. In that case, the sort toggles between asc /des, which I do not want to happen. PHP Code:

Sorting Table Results
I am working on a spreadsheet / table layout and want my users to be able to sort by the various columns in the table. The table heading descriptions and the data are in two MySQL tables. Currently, my thinking is that the best way to do this is insert an image (up arrow or down arrow) below the header row in the html table that the user will click to sort assending or descending by that column. I currectly can dynamically create the table heading, inset the arrow image in all of the row two cells and retrieve the data into the table. Although I have been able to insert a hyperlink with the image, it hasn't done me much good. Code:

Problem Sorting By 2 Fields From Table
As part of a rating system on my site, data for the total rating and also the number of votes gets added into a table. I am currently trying to query this table to get the highest rated row of data. This worked fine when I only had "ORDER BY rating DESC LIMIT 1" at the end of my query - It would select the row where the rating was 5 out of 5. I realised that if 2 rows had the same rating, I could not determine which one to select. So i tried changing the code to: "ORDER BY rating, num_votes DESC LIMIT 1". For some reason, this now selects a row where both the rating and num_votes values are 0. Just in case you need to see the entire query, here it is:

Advice On Sorting Results (in A Table): Session Variables?
I have a table of query results (from PostgreSQL) that I am displaying using PHP. I would like to give the user the option to sort the results by clicking on one of the various table headings. I know that I can sort them at the time that I query them, but this would require a new database query each time. I am thinking of making the heading a hyperlink similar to the following: <a href=myresultspage.php?sort=price> //this would be the link to sort by the price collumn. I have managed to make a simple sorting function, by putting the results into an array then sorting the array by the appropriate dimension of the array as indicated by the value of $sort. My question is this: If I keep the results in an array, how can I pass the array when the user clicks on the hyperlink that tells which collumn to sort by? Do I need to use session variables? It doesn't seem like I can pass an array as a GET variable.

Sorting Is Better Than MySQL Sorting?
I've had a few people come to me and tell me that they are able to sort huge amounts of data better in PHP than MySQL (as to how they go about that I didn't inquire since I thought it to be a little odd). Now, I know if you're returning only 100's or even 1000's of rows then a simple ORDER BY clause will work fine (better than developing a sorting algorithm in PHP). However, I can't seem to see where PHP would be better at sorting than MySQL. Does anyone have any experience with PHP being a better choice to sort something than MySQL?

MySQL Sorting
I'd like to do is divide results from a MySQL query over multiple pages, each holding a certain number of results. Now I have a PHP script that uses the MySQL command LIMIT in the query to get # results at a time (which also means not all the results are returned every time, just a few, obviously this is a good thing for speed/load so I wanna keep it that way). The MySQL manual states that if you use LIMIT # with ORDER BY, MySQL will end the sorting as soon as it has found the first # lines Ok I could've posted this on the MySQL forum first but actually I was wondering whether someone has a solution in PHP for this?

PHP/MySql Sorting Difficulties
I have written a sorting engine which displays non expired records, but im having difficulties getting it to work. It was working fine until I added pagination, and now it seems to have gone to pot. The script works by getting todays date, and based on the users selection from the drop down menu, calculates the number of pages, and records the users sort preference. The correct number of links to different pages are then generated, and the pages are populated based on the users sort preference, or so I thought... The first page of results is sorted correctly, but on the second and subsequent pages, this isnt always the case. This causes results to be appearing in the wrong order, or not at all in some cases. Ive included my source code, if anyone see's anything which is glaringly obvious, or feels like giving me a hand fixing this id very much appreciate it :) <!-- This is the HTML Form where the user selects if they wish to sort or search for records --> .......

I'm using the Pear DB for connecting to my mySQL database. Based on the example rows I gave, Mary Jane would go first, and then John Smith. How would I go about doing this? I was beginning to split the result based on spaces, and the last word to explode, but how would I truly do this?

So I have duplicates in my echoed list. Is there a way to have the data sort so the duplicates do not appear, and the email will only appear once on the list?

I have a page that gets a list of magazine article titles stored in a MySQL database. The output is sorted and formatted all nicey nice. I am wondering if there is an easy way, or some trick, that I can use to place headings in between the category listings for the articles. Allow me to explain. Let's say there are 15 articles 5 of them are category A; five of them are category B; the last five are category C. Right now I am sorting them fine. With one database call can I insert an image or text header (and possibly an <a href>) between A and B to denote the next category? I can do it with several database queries, but I'd like to avoid that if possible.

Using PHP To Sort Data In MySQL Table 1 By Values In Table 2
I have a MySQL database with 2 tables in it. products and prices.. Products has a field in it called 'prodno'. Prices has a field in it called 'prodid'. There is one of each item in products and each product has it's own unique 'prodno' There are multiple instances of each product's pricing in prices.. One for each price.. So if a product had multiple prices depending on quantity it would have an entry for each price.. Example: id = 1 prodid = 7001 qty = 300 price = 12.5 id = 2 prodid = 7001 qty = 400 price = 15.5 I was wondering if I could query the database getting info from the products table but sort it according to the prices in the prices table. Kinda like doing a "SELECT * FROM products" ordering it by the lowest price value from each item.. This is all very confusing to me, and I'm the one writing it. Let's try one last time.. Query the database selecting * from products (I plan on using all the info in products) and ordering them by the lowest price for each item in the prices table. I've tried sorting the results of just a basic SELECT * FROM products using Javascript and PHP but with pagination in the results it makes it a bit hard.
