  • How can I use a php array in a mysql search query?

    - by ThinkingInBits
    I was going to use the scuttle solution on: http://www.pui.ch/phred/archives/2005/04/tags-database-schemas.html for handling searches on my website. I was wondering how I could take the search input from a user and turn it into a single query. For instance, let's say a user inputted 'blue dogs' in their search query... How could I dynamically update the query to include ('blue', 'dogs') in union and intersection queries?

  • I'm new to OOP/PHP. What's the practicality of visibility and extensibility in classes?

    - by marcdev
    I'm obviously brand new to these concepts. I just don't understand why you would limit access to properties or methods. It seems that you would just write the code according to intended results. Why would you create a private method instead of simply not calling that method? Is it for iterative object creation (if I'm stating that correctly), a multiple developer situation (don't mess up other people's work), or just so you don't mess up your own work accidentally?

  • Is there a simple way to "roll your own forms" for mysql in php, for example in jquery?

    - by talkingnews
    I've been googling around for a really simple way of making what is, in effect, nothing more than an enhanced phpMySql. In a mysql database, I have: Name, address, phone, website etc, plus 2 or 3 custom fields. This data is pulled out to make a website. All I want is to be able to make a freeform form, a bit like Access, but for the web, and the only thing I want to do over and above normal field editing would be to have a list of when I contact them, what was said, and perhaps a reminder when the next action is due. I've looked at so many CRMs my mind is boggling, and they all do WAY more than I need. I don't have leads or accounts, all I have is the need to make sure than when I update the person's details, and for that data to be in the same DB as my site is generate from. I'm happy to learn if I can get pointed in the right direction, and I have a feeling that something like what I want might lie in the direction of jquery. It's just that there's so much good jquery stuff about, I can't see the wood for the trees! Thanks.

  • How can I organize many results in a selectbox using php?

    - by zeckdude
    I have a select box that is part of a form. It is currently querying the addresses table and displaying the addresses into the select box. I plan on having up to 100 addresses. I'm looking for a solution where I can show all the states if the user clicks on the select box. Then if the user hovers over a state it will show all the addresses for that specific state. Then if the user clicks on an address, it will show that as the picked option in the select box. This is like a dropdown menu within a select box. Does anyone know where I can find a solution as this?

  • What Gotchas When Learning C++, If I came from PHP/Java?

    - by silent
    Hi, I need to learn C++ in order to learn building Nokia WRT and or maemo application. I need to know what gotchas and what aspect of C++ that I need/have to learn or focus more. One thing I got in my mind is that C++ doesn't have garbage collector. Therefor, I need to focus on variable type. But, is there any others that really important and I can't ignore it?

  • PHP OOP Design Patterns: Should I Create two seperate classes for registration and form validation?

    - by Joshua Poshua
    So here's my problem: I have two types of registration, registration A and registration B, each will have some of the same fields and some different fields. I was going to create abstract class registration and both A and B would have their own classes that extend from registration. My question is, should I create a seperate Validation class with seperate A and B validation classes that extend? or is there a better pattern to use for something like this? Thanks

  • How do I flatten an associative array into an array with only values in PHP?

    - by aalaap
    I have an array that has keys and values. For eg: Array ( [name] => aalaap [age] => 29 [location] => mumbai ) I want to convert the keys from this into values, but I want the values to apear right after the keys. For eg: Array ( [0] => name [1] => aalaap [2] => age [3] => 29 [4] => location [5] => mumbai ) I can easily write an iteration function that will do this... for eg: array_flatten($arr) { foreach ($arr as $arrkey => $arrval) { $arr_new[] = $arrkey; $arr_new[] = $arrval; } return $arr_new; } ...but I'm trying to find out if there's any way this can be accomplished using array_combine, array_keys, array_values and/or array_merge, preferably in one, so i don't need to use a custom function. Is there?

  • Why does a PHP function with no parameters require parentheses?

    - by MarkRobinson
    I just spent 3 hours wondering why I couldn't start a session, then realised that I used: session_start; when I should have used: session_start(); I received no error messages at all! Perhaps then, I thought, it's a lazy way to differentiate functions from variables - but then remembered that it can't be as variables require a $ Can anyone tell me why parentheses are required then, and also why no error is given when they aren't used?

  • PHP output of foreach loop into a new array.

    - by RobHardgood
    I know I'm probably missing something easy, but I have a foreach loop and I'm trying to modify the values of the first array, and output a new array with the modifications as the new values. Basically I'm starting with an array: 0 = A:B 1 = B:C 2 = C:D And I'm using explode() to strip out the :'s and second letters, so I want to be left with an array: 0 = A 1 = B 2 = C The explode() part of my function works fine, but I only seem to get single string outputs. A, B, and C.

  • Fastest way to represent a collection of bits in PHP?

    - by Piskvor
    What is a good way to represent a collection of bits? I have a set of various on/off toggles (thousands of them) and need to store and retrieve their state. The naïve implementation would be an array of booleans, but I'm wondering if there's a better way (better in terms of access speed and/or memory requirements). I've found this BitArray implementation, but it's limited to 32 bits, which is not enough for this case.

  • Creating a global variable on the fly. [PHP ENCRYPTION]

    - by stormdrain
    Is there a way to dynamically create constant variables on the fly? The idea is that upon logging into the system, a user would be asked to upload a small text file that would be fread, and assigned to a var that would be accessible throughout the system. If this is possible, just to be clear, would this variable then only be accessible to that user and only while the session is alive? Security being the main concern here, would it be more practical to store the var in a session variable? The plan: Data in the db will be encrypted via mcrypt, and the key will be stored on USB thumbdrives. The user will insert the thumbdrive when going to access the system. Upon logging in, the app will prompt the user to upload the key. They will navigate to the thumbdrive and key. Via fopen and fread, the key will be assigned to a global var which will then allow access to encrypted data, and will be used to encrypt new info being entered to the db. When the user logs out, or session times out, the global var will become empty. Thanks!

  • How would I find all sets of N single-digit, non-repeating numbers that add up to a given sum in PHP

    - by TerranRich
    Let's say I want to find all sets of 5 single-digit, non-repeating numbers that add up to 30... I'd end up with [9,8,7,5,1], [9,8,7,4,2], [9,8,6,4,3], [9,8,6,5,2], [9,7,6,5,3], and [8,7,6,5,4]. Each of those sets contains 5 non-repeating digits that add up to 30, the given sum. Any help would be greatly appreciated. Even just a starting point for me to use would be awesome. I came up with one method, which seems like a long way of going about it: get all unique 5-digit numbers (12345, 12346, 12347, etc.), add up the digits, and see if it equals the given sum (e.g. 30). If it does, add it to the list of possible matching sets. I'm doing this for a personal project, which will help me in solving Kakuro puzzles without actually solving the whole thing at once. Yeah, it may be cheating, but it's... it's not THAT bad... :P

  • PHP: best practice. Do i save html tags in DB or store the html entity value?

    - by Matt
    Hi Guys, I was wondering about which way i should do the following. I am using the tiny MCE wysiwyg editor which formats the users data with the right html tags. Now, i need to save this data entered into the editor into a database table. Should i encode the html tags to their corresponding entities when inserting into the DB, then when i get the data back from the table, not have the encode it for XSS purposes but i'd still have to use eval for the html tags to format the text. OR Do i save the html tags into the database, then when i get the data back from the database encode the html tags to their entities, but then as the tags will appear to the user, i'd have to use the eval function to actually format the data as it was entered. My thoughts are with the first option, i just wondered on what you guys thought. Thanks M

  • What's the best way to format long strings of HTML in PHP?

    - by dclowd9901
    I know it's really a subjective question, but for best-practices (and readability), I can't seem to get a fix on the best way to format long strings of HTML. I typically do it like this: echo ' <div> <p>Content Inside</p> <div class="subbox"> <ul> <li>etc.</li> <li>etc.</li> <li>etc.</li> <li>etc.</li> </ul> </div> </div> '; But I still don't like the outcome, especially if this appears in the middle of a large block of code. It just feels messy.

  • Is there any way to achieve multiple inheritance in php?

    - by Starx
    Lets say I have a parent class class parent { } ..... This parent has three sub class class child1 { } class child2 { } class child3 { } and these child classes have further smaller parts like class child1subpar1 { } class child1subpar2 { public function foo() { echo "hi"; } } class child2subpar1 { } class child2subpar2 { } Now, how to sum this whole up like class child1 extends child1subpar1, child1subpar2 { } class child2 extends child2subpar1, childsubpar1 { } class parent extends child1,child2,child3 { } I need to execute the methods in its inherited classes and do something like this $objparent = new parent; $objparent - foo();
