Natively Connect to JotForm Data in PHP


Create PHP applications on Linux/UNIX machines with connectivity to JotForm data. Leverage the native support for ODBC in PHP.

Drop the CData API Driver for ODBC into your LAMP or WAMP stack to build JotForm-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to JotForm data, execute queries, and output the results.

Using the CData ODBC Drivers on a UNIX/Linux Machine

The CData ODBC Drivers are supported in various Red Hat-based and Debian-based systems, including Ubuntu, Debian, RHEL, CentOS, and Fedora. There are also several libraries and packages that are required, many of which may be installed by default, depending on your system. For more information on the supported versions of Linux operating systems and the required libraries, please refer to the "Getting Started" section in the help documentation (installed and found online).

Installing the Driver Manager

Before installing the driver, check that your system has a driver manager. For this article, you will use unixODBC, a free and open source ODBC driver manager that is widely supported.

For Debian-based systems like Ubuntu, you can install unixODBC with the APT package manager:

$ sudo apt-get install unixodbc unixodbc-dev

For systems based on Red Hat Linux, you can install unixODBC with yum or dnf:

$ sudo yum install unixODBC unixODBC-devel

The unixODBC driver manager reads information about drivers from an odbcinst.ini file and about data sources from an odbc.ini file. You can determine the location of the configuration files on your system by entering the following command into a terminal:

$ odbcinst -j

The output of the command will display the locations of the configuration files for ODBC data sources and registered ODBC drivers. User data sources can only be accessed by the user account whose home folder the odbc.ini is located in. System data sources can be accessed by all users. Below is an example of the output of this command:

DRIVERS............: /etc/odbcinst.ini SYSTEM DATA SOURCES: /etc/odbc.ini FILE DATA SOURCES..: /etc/ODBCDataSources USER DATA SOURCES..: /home/myuser/.odbc.ini SQLULEN Size.......: 8 SQLLEN Size........: 8 SQLSETPOSIROW Size.: 8

Installing the Driver

You can download the driver in standard package formats: the Debian .deb package format or the .rpm file format. Once you have downloaded the file, you can install the driver from the terminal.

The driver installer registers the driver with unixODBC and creates a system DSN, which can be used later in any tools or applications that support ODBC connectivity.

For Debian-based systems like Ubuntu, run the following command with sudo or as root: $ dpkg -i /path/to/package.deb

For Red Hat systems or other systems that support .rpms, run the following command with sudo or as root: $ rpm -i /path/to/package.rpm

Once the driver is installed, you can list the registered drivers and defined data sources using the unixODBC driver manager:

List the Registered Driver(s)

$ odbcinst -q -d CData API Driver for ODBC ...

List the Defined Data Source(s)

$ odbcinst -q -s CData API Source ...

To use the CData API Driver for ODBC with unixODBC, ensure that the driver is configured to use UTF-16. To do so, edit the INI file for the driver (cdata.odbc.api.ini), which can be found in the lib folder in the installation location (typically /opt/cdata/cdata-odbc-driver-for-api), as follows:

cdata.odbc.api.ini

... [Driver] DriverManagerEncoding = UTF-16

Modifying the DSN

The driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties. Additionally, you can create user-specific DSNs that will not require root access to modify in $HOME/.odbc.ini.

Start by setting the Profile connection property to the location of the JotForm Profile on disk (e.g. C:\profiles\JotForm.apip). Next, set the ProfileSettings connection property to the connection string for JotForm (see below).

JotForm API Profile Settings

You will need to find your JotForm API Key in order to authenticate. To obtain an API Key, go to 'My Account' > 'API Section' > 'Create a New API Key'. Once you've created your new API Key, you can set it in the ProfileSettings connection property.

Custom Enterprise API Domains

Enterprise customers of JotForm are given custom API domains to connect to, rather than the default 'api.jotform.com' domain. If you are an enterprise JotForm customer, then set Domain to you custom API hostname, such as 'your-domain.com' or 'subdomain.jotform.com', inside the ProfileSettings connection property. Conversely, if you do not have a custom domain and still need to connect to 'api.jotform.com', then leave Domain undefined and set only APIKey.

/etc/odbc.ini or $HOME/.odbc.ini

[CData API Source] Driver = CData API Driver for ODBC Description = My Description Profile = C:\profiles\JotForm.apip ProfileSettings = 'APIKey = my_api_key Domain = my_custom_domain'

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Establish a Connection

Open the connection to JotForm by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.

$conn = odbc_connect("CData ODBC API Source","user","password");

Connections opened with odbc_connect are closed when the script ends. Connections opened with the odbc_pconnect method are still open after the script ends. This enables other scripts to share that connection when they connect with the same credentials. By sharing connections among your scripts, you can save system resources and queries execute faster.

$conn = odbc_pconnect("CData ODBC API Source","user","password"); ... odbc_close($conn); //persistent connection must be closed explicitly

Create Prepared Statements

Create prepared statements and parameterized queries with the odbc_prepare function.

$query = odbc_prepare($conn, "SELECT * FROM Forms WHERE Status = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC API Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Forms WHERE Status = ?"); $success = odbc_execute($query, array('ENABLED'));

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC API Source","user","password"); $query = odbc_exec($conn, "SELECT Id, Title FROM Forms WHERE Status = 'ENABLED'");

Process Results

Access a row in the result set as an array with the odbc_fetch_array function.

$conn = odbc_connect("CData ODBC JotForm data Source","user","password"); $query = odbc_exec($conn, "SELECT Id, Title FROM Forms WHERE Status = 'ENABLED'"); while($row = odbc_fetch_array($query)){ echo $row["Id"] . "\n"; }

Display the result set in an HTML table with the odbc_result_all function.

$conn = odbc_connect("CData ODBC JotForm data Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Forms WHERE Status = ?"); $success = odbc_execute($query, array('ENABLED')); if($success) odbc_result_all($query);

More Example Queries

You will find complete information on the SQL queries supported by the driver in the help documentation. The code examples above are JotForm-specific adaptations of the PHP community documentation for all ODBC functions.
