Native PHP Barcode Generator Script User Manual
The PHP Barcode Generator is a server-side script that adds barcode generation capability to any PHP-compatible website. Once installed, linear barcode images are generated on the server in memory and streamed to the client without saving any temp files on the server.
- After extracting the install files from the demo or purchased download, copy the necessary files to a webserver where PHP script processing is enabled. Each file contains the name of the barcode symbology that it supports.
- Open the file in a web browser and verify that a default barcode image is displayed. If it is not, ensure that the files are installed in the proper folder on the server and verify that PHP script processing is active in the folder where the file resides.
- Integrate the resulting URL into your web application as a dynamic IMG tag and add the D= parameter for the data that is being encoded into a barcode. This script may be streamed in the same way as the Streaming Barcode Server for IIS, which offers several examples for integrating streaming barcodes.
- Refer to the Barcode Script Parameters section
of this user guide to modify additional parameters such as apply tilde, font
size and more. For example, the following parameters can be utilized to encode
the text of "123456", disable the optional check digit in Code 39 and set the bar
height to 30 pixels:
Default values should be used for all properties unless specific requirements dictate otherwise.
|Apply Tilde||PT||F||When True in Code 128
with the Auto character set, the format
~??? may be used to specify the
ASCII code of
the character to be encoded and several other
Options are enabled including encoding of GS1-128 AIs.
*Valid in idautomation-code128.php only
|Bar Height||BH||40||The pixel height of the barcode.|
|Check Character||CC||T*||Automatically adds the
check digit to the barcode when equal to 'T'.
*F is the default in Code 39; LOGMARS requires this parameter to be true.
|Check Character in Text||CT||T||Automatically adds the check digit that is encoded in the barcode to the human readable text that is displayed when equal to 'T'.|
|Data Encoded||D||123456789012||The data that is to be encoded in the barcode.|
|Narrow to Wide Ratio||N||2||The narrow-to-wide ratio of symbologies that contain only narrow and wide bars such as Code 39, Interleaved 2 of 5 and MSI. Valid values are 2 and 3.|
|Orientation||O||0||The orientation of the barcode. Valid values are 0, 90, 180 and 270.|
|ShowText||ST||T||If set to F, the human readable text interpretation will not be displayed with the barcode.|
|XDimension in pixels||X||1||The number of pixels to determine the overall barcode width. Default = 1 which is 1/96 of an inch and about 12 MILS.|
|Font Size||FS||12||The font size used for
human readable text.
*Only values of 10 and 12 are applicable. Other values must be implemented manually by displaying a text field below the barcode.
|Data Matrix Specific||Parameter||Default||Property Description|
|Process Tilde||PT||T||When set to "F", the tilde "~" functionality will not be processed. As explained in the Data Matrix FAQ, the tilde is used for GS1-DataMatrix and encoding ASCII codes.|
|Encoding Mode||MODE||3||The Encoding Mode for data being encoded. Valid parameters are 0=BASE256, 1=C40, 2=TEXT and 3=ASCII. To encode GS1-DataMatrix, ensure MODE is set to "3", the default.|
|Preferred Format||PFMT||0||Sets the preferred format represented by a number; valid values are from 1 (10X10) to 24 (144X144) and from 25 (8X18) to 30 (16X48); the default value of '0' is used for automatic formatting. If the component needs more space to create the symbol, this property will be ignored.|
|Process Tilde||PT||T||When set to "F", the tilde "~" functionality will not be processed. As explained in the QR-Code FAQ, the tilde is used for GS1-QRCode and encoding ASCII codes.|
|Error Correction Level||ECL||M||The level of error correction. Valid values are L, M, Q & H.|
|Encoding Mode||MODE||B||The Encoding Mode. Valid values are B (binary), A (alphanumeric) and N (numeric).|
|Process Mask||PM||T||When set to F the mask is not optimized, which will improve processing time when generating many barcodes at the same time.|
|Version||V||1||The version of the symbol. Setting this value to -3 can generate a Micro QR Code symbol.|
Only commonly used parameters are included in the script generator files, ensuring quick and efficient PHP barcode generation. If additional properties or symbologies are needed, such as USPS IMb, DataBar or PDF417, the functionality of this PHP product is also available as a service hosted on IDAutomation's fault tolerant servers. The service is an easy way to generate barcodes without installing any software.
