Installing php_zip on Linux


This is an error that I encountered with while using PHPExcel. It is a library written in pure PHP and providing a set of classes that allow us to write to and read from different spreadsheet file formats, like Excel (BIFF) .xls, Excel 2007 (OfficeOpenXML) .xlsx, CSV, Libre/OpenOffice Calc .ods, Gnumeric, PDF, HTML, etc. This library is built around Microsoft's OpenXML standard and PHP. The requirements of this library are :

  • PHP version 5.2.0 or higher
  • PHP extension php_zip enabled (required if you need PHPExcel to handle .xlsx .ods or .gnumeric files)
  • PHP extension php_xml enabled
  • PHP extension php_gd2 enabled (optional, but required for exact column width auto-calculation)

While I was working on a project, I didn't check if all dependencies for PHPExcel were met. I wrote the program. It was fine when I was writing to the old .xls file format but as I wanted to write for .xlsx I got this error. This error was a resultant of unmet dependency of php_zip.

Fatal error: Class 'ZipArchive' not found in/var/www/vhosts/example.com/httpdocs/nomina_virtual/Classes/PHPExcel/Writer/Excel2007.php on line 226
So how do we solve this issue. Its pretty simple with PECL which is a repository of PHP extension that are made available to us via the PEAR packaging system. The single step solution to this is

#pecl install zip
You just have to run this command in terminal and you'll have php_zip installed in your system with php_zip enabled in  php.ini automatically.

Automate file upload in Selenium IDE

Image
Selenium IDE is an integrated development environment for Selenium tests. It records your interactions with websites to help you generate and maintain site automation, tests, and remove the need to manually step through repetitive tasks. Selenium IDE can be installed in Google Chrome from  here . For Firefox visit this  link . File upload in Selenium IDE cannot be automated simply by recording from the IDE. Because when we select the file input field, the dialog that opens up is a system window which cannot be controlled by Selenium IDE. Therefore, clicking the input file field to select a file will not work. Also the selected file path is changed to C:\fakepath\filename.extension. So to fix this issue, we need to configure the browser to support file upload and then instead of clicking the input field we set the file using ‘type’ selenium command which is shown below. First, to support file upload in Selenium IDE, configure your browser to support file upload: Visit ‘...
