Putting An Array In A Mysql Database Table Field
I want to insert an array into my database but i've got a problem with it. Before i insert the array into the dbase i check if everything is in the array with print_r($array). Everything that should be in the array is in there so i insert it into the dbase. When i check my dbase with phpmyadmin the field that should contain my array has the word array in it so i assume the array is in the dbase. But when i retrieve the data from my dbase and check my array with print_r i get the following error: Warning: Argument to array_values() should be an array in.
Valid MySQL Database/table/column Name Regexp
regular expression in PHP which could be used to check that a proposed (My)SQL database/table/column name is valid, i.e. shouldn't result in an SQL error when created? The user of my (hopefully to be opensourced) program has the ability to create database/table/column names on the fly. I'm aware of obvious characters such as ., [space], things like >, etc., which won't work, but haven't been able to source a definitive list, including having googled the MySQL site. Obviously certain characters need to be filtered out, as noted above, but I want to be as unrestrictive as possible; hence just [a-z]* isn't good enough because things like _ are acceptable. Ideally, I'd prefer a regexp that applies to _all_ vendors' databases, not just MySQL as I'm about to migrate the program to being database-independent, probably using PEAR DB, but even a MySQL-specific regexp would do the job. In the longer term, I plan some sort of entity conversion script so that theoretically any character could be used, using some sort of escaping mechanism probably.

Delete From Database
I have code that does not delete from a database. The same code (cut an paste in the same file, but different function and having a different query) works. So, of course, I tested the query interactively. I echoed the query and did a cut and paste when interactively connect to the database. That one worked so it isn't the query since interactively it is seeing exactly the same thing as the code produces. Here is the code: function deleteCatalog($catalog) { $query = "DELETE FROM CatalogNames WHERE sCatalogID='" . $catalog . "'"; mssql_select_db($database_Login, $_SESSION['Login']); $result = mssql_query($query, $Login); ... } The $query echos: DELETE FROM CatalogNames WHERE sCatalogID='CMP' As an example of code that works (in the same file) function addToCatalog($cat_id, $cat_name) { $query = "INSERT INTO CatalogNames (sCatalogID, sCatalogName) " . "VALUES ('" . $cat_id . "', '" . $cat_name . "')"; mssql_select_db($database_Login, $_SESSION['Login']); $result = mssql_query($query, $_SESSION['Login']); ... } The second and third lines are identical (cut and pasted) as in other places in the same code. In fact, it is only in this file that I do all the database work. Every other function works. This is the only delete, however.

Flat File Database System?
I am researching flat file DBs. I know that they are bad, but a client i am working for does not have access to mysql hosting! What i need to do is to have a set of special offers (say about 8 different special offers, each one consisting of 5 fields (title, link, description, image, end date)).

Comment System Database Structure
I'm sure this has been brought up numerous times in the past, but I couldn't find any posts asking it specifically. I am creating a comment system for a news site.. and my question is: does it make more sense to have one table containing all comments relating to all stories, calling the comments by story ID, or to create an individual table for each story containing just the comments specific to that story?

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.
Content Management System Using Backend Database
Can I ask some advice in regards database solutions and content management solutions.? Do you have a philosophy on what is the best for databases - ASP, JSP, Cold fusion, PHP, etc. My company website site is going to be rebuilt and I am the lucky one to do this but I am unsure of the needs and complexity of the project, and what would be the best base code. Do you have any thoughts in this area? The site requires functionality like display projects, archive projects, sort projects by date, project location, group company, etc. All images and pdfs are currently uploaded through the content management solution, however we will have to implement a new content management solution as well. Do you know of an easy to use product that functionally work well in content management? Do you know of any products on the market that are like WYSIWYG database solutions?

My Script Pauses - No Calls To Database Or File System - But A Long Pause
There is a point in rendering a page of mine where my script pauses for a long time. It is a painful wait - maybe 5 seconds. It is long enough that when I try to show the software to people they get bored at that point and begin to look away. I'd like to remove whatever road block slows things down at that point in my script, but I am unable to diagnose the problem. I am using a command that is used elsewhere on the page, before and after, without delays. There are no calls to the database or the file system.

MySQL - Delete Across Two Tables. OT
i cant find the MySQL newsgroup, however i am hoping to pick up on some expert advice from php/mysql gurus here. I'm having some trouble performing a delete across two tables. The tables i have are: questionnaires (id, name); questionnaire_questions (questionnaires_id, id, name, qf_type) The questionnaire_questions table contains a list of questions for a specific questionnaire (indicated by the questonnaires_id). I would like to remove a questionnaire, and when doing so all corresponding questionnaire_questions who have matching id's (questionnaires.id = questionnaire_questions.questionnaires_id). I have this statement, however it only works if a questionnaire has questions... however i would like it to delete even if no questions exist for that specific questionnaire. The SQL i am using is: delete questionnaires, questionnaire_questions FROM questionnaires, questionnaire_questions WHERE questionnaires.id = questionnaire_questions.questionnaires_id AND questionnaires.id = THE_QUESTIONAIRE_TO_DELETE_ID
DELETE Problem With MySQL
I've been learning using PHP and MySQL from the tutorial at freewebmasterhelp.com. Everything works fine, except deleting things. The script is invoked with a URL like this: http://www.example.org/test/delete_entry.php?id=35 And here's the script: <? include("dbinfo.inc.php"); $id = $_POST['id']; mysql_connect($server, $user, $password); $query = "DELETE FROM test1 WHERE id = '$id'"; @mysql_select_db($database) or die("Unable to select database."); mysql_query($query); mysql_close(); header("Location: entries.php"); ?> The dbinfo.inc.php file defines the variables $server, $database, $user and $password. The login part works.

How To Delete Only Certain Text In A Mysql Row?
I have a table setup that has a column setup as friends and users can add friends to this column no problem. What I would like to know is how to delete only certain parts of the text of the row/cell where their friends are stored. The friends text is seperated by the following : " , " That is a space on either side and comma in the middle of the space. I know how to explode the results and put into an array to display the reuslts, but is there a way to delete only one of the friends if the text is as follows. , thomas , frank , irene , I think you can get the idea.

Php/mysql Insert, Update, Delete All-in-one
I have a check box form in an admin area, that links various related tables into one. These check box results are stored in an array, and then looped, there are in fact four groups of arrays, but the array length could become large (i.e. dozens - not hundreds) The issue I have is that from the one form multiple things need to occur. - If a box is checked and the record doesn't exist a new record needs to be inserted. - If a box is checked and the record does exist, it should be ignored (as it already exists). - If the box is unchecked and the record exists, it should be deleted. - If the box is unchecked and the record doesn't exist it should be ignored (the record doesn't exists). I'm looking for the logic and process (rather than being hand fed code ) Can this be done with 1 (or more likely 2) sql statements. Or do I have to loop thru the arrays, checking the existance and then applying a specific sql statement depending upon checked status and the records existance. Someone mentioned using IF() in the sql statement, but I am not familiar with that one.
