EZ Query by Skorch

This was designed mainly to display data. I also assumed that only webmasters would be using the alter db commands. I use it with dynamic URL's and a apache mod-rewriter. I store each page in a db row and one page displays the information from a specific Database row, defined by the dynamic URL.

You must open EZQuery with a text editor and change the function db to reflect your personal MySql settings. I indicated by Capitalizing the required info.

Then for each page that requires a MySql connection.

function list

db->constructor set->choose db table and/or field stash->string prep dash->oppo of stash ezq->fetch query upq->update table inq->add row to table

I made this class to interface with a MySql database. The core function is Ezq. Before this class can be used you must use the function set(It has two modes, specific and all). Most queries use the vars that this function sets I did this so a programmer had ultimate control over where information came from or where it goes. Once you are familiar with how this class works you will be able to make any mysql SELECT clause. The Stash and Dash functions can(and really should) be expanded to meet your specific needs.

Detailed use of function inputs

db- This function establishes a db connection. It is also the constructor and has no input. output is db connection The first line of any extended class' constructor should be make a new db object. it has no input and should be hardcoded with your mysql db

set(table,*/field)- This function allows you to select which table to get data from,It uses class var $from. Input is table name Presets class Var $from. $col is another class var If text is entered as the second parameter you can set field name too. set to 0 otherwise (uses "SELECT * FROM table" rather than "SELECT field FROM table")

stash(string)- This function adds html entities and slashes. Input is one string(user subbed) output is string

dash(string)- This function gets rid of added slashes. Input is one string(from db) output is string

ezq("field=value",0)- This function returns an associative array from the db or performs a query. Inputs are Complete WHERE clause "field=value" and an integer. If integer is equal to 12 a basic query will be done(for use with mysql functions other than fetch assoc. If it's not equal to 12 a assoc array will be fetched at the end of the first parameter you can add extra mysql functions like order by or limit

inq(table,array of values)- This is the insert command. It has no string val at moment. It returns status of attempted query. Inputs are Table-Name AND array-of-values

upq(field=value,array of combined fieldnames and values)- This is the update row. This is the most difficult function to use being that the SET statement must be built. First is the where statement(field=value) and an array. Each array line must contain "fieldname=desiredvalue" field1=value1,etc I made this process automated for myself by naming fields that can be updated(you are planning and outlining your project?)

text1,text2,text3

then I just

FOR loop linking the relevant result to the relevant field. i.e. FOR($i=1;$i > 4;$i++){$array[$i]='text'.$i.'='.$value[$i];} $this->upq('field=value',$array);
