![]() Inventory Search App /** this is boiler plate code from: converts array of form elements to associative array * */ $. The searchInventory function that gets triggered on click of the search button does most of the work by packaging the form search variables into a json request, handing it off to the php script, and then processing the json dataset that comes back.Ī good portion of the code uses JQuery idioms and functions. Also not much in the way of error handlers. JQuery Client-side Codeįor the client side JQuery side, we did away with all that css fanciness to make this short. To keep it short, we just put the connection string right in the php script and did away with all the try / catch logic we usually put in. That said the PHP part is fairly trivial to swap out with something likeĪSP.NET and most other web server side languages. Most of the work is happening in the JQuery client side tier and the database part we already saw. This example requires PHP 5.1+ since it uses the pg_query_param function introduced in PHP 5.1. Simple that we are just going to use the raw PHP PostgreSQL connection library directly. Normally we use a database abstraction layer such as ADODB or PearDB, but this is so The PHP part is fairly minimalistic just involving a call to the database and return a single row back. If you don't move Postgres.app to the Applications folder, you will see a warning about an unidentified developer and won't be able to open it. Download Move to Applications folder Double Click. This time we'll put our stored function to use in a real web app built using Postgres.app can install minor updates automatically, so you get bugfixes as soon as possible. We generated the search request using PostgreSQL.Īs mentioned, in practice, the json search request would be generated by a client side javascript API such as JQuery. ![]() ![]() It is recommended you follow the quickstart for the 2nd generation PHP 7.2 runtime. NOTE: This repository is for the App Engine PHP 5.5 runtime. We demonstrated how to create a PostgreSQL PL/Javascript stored function that takes as input, a json wrapped search request. Guestbook demo for Google App Engine that uses PHP. In our last article, PL/V8JS and PL/Coffee JSON search requests
