How do I use Ajax and Jquery to pull information off a PHP database, and populate elements with that information? -


I'm tweaking a website so employees are easy to edit products. Now, someone has to enter DB and prices have to be changed, and then someone has to change the physical HTML of the website.

So I am writing code which pulls all the products from DB, and displays them on a page that can be edited. I think it would be best to do everything with Ajax.

ajaxRequest.open ("GET", URL, true); AjaxRequest.send (zero);

The problem is, I know about processing Ajax requests using only one URL (using POST, GET, etc). I need help in writing code for pulling information about DB, and displaying it.

The table name is the products within the column ID, stock, SHORTNAME, description, PRICE and shipping.

In HTML, I have a div setup:

I want to set it so that I can click on a button, AJAX pulls all information from PRODUCT, and creates .productName div I If the user clicks on .productName , then it will proceed to appear .productDesc .

Question: How can I ask DB by using AJX on one click, and insert information into elements?

Ajax can not access your database. Ajax simply loads the contents from the URL. Your application should do this, and the result must be provided in the form of an AJAX call.

How it will work here.

  1. Browser opens a URL on your server
  2. provides a page for display on PHP browsers
  3. User clicks a few
  4. Javascript sends an Ajax request to your server
  5. PHP receives this request and
  6. PHP provides a response to the request
    7. < Li> Ajax handler on your page gets this feedback as plain text and with it Something interesting happens (such as an inserted HTML, evaluation of JSON, or Javascript executed)

Ajax is actually a way to load a response from your browser without navigating to that page . It should not (and should not be) any kind of direct database access. In fact it is not known that there is a database at all.

Imagine the safety issues if any JavaScript can read or write any field in your database. This will be a hacker dream.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
