| 65 | <h1>Database Export Class</h1>
|
| 66 |
|
| 67 | <p>The Database Utilities Class contains functions that help you export your data.</p>
|
| 68 |
|
| 69 | <p class="important"><strong>Important:</strong> This class must be initialized independently since it is a separate class from the main Database class.
|
| 70 | More info below...</p>
|
| 71 |
|
| 72 |
|
| 73 | <h2>Initializing the Export Class</h2>
|
| 74 |
|
| 75 | <p>To initialize this class please use the following code:</p>
|
| 76 |
|
| 77 | <code>$this->load->dbexport()</code>
|
| 78 |
|
| 79 | <p>You can also autoload this class from within your <dfn>config/autoload.php</dfn> file by specifying <kbd>dbexport</kbd> in the <samp>$autoload['libraries']</samp> array.</p>
|
| 80 |
|
| 81 | <p>Once initialized you will access the functions using the <dfn>$this->dbexport</dfn> object:</p>
|
| 82 |
|
| 83 | <code>$this->dbexport->some_function()</code>
|
| 84 |
|
| 85 |
|
| 86 |
|
| 87 | <h2>$this->dbexport->cvs_from_result($db_result)</h2>
|
| 88 |
|
| 89 | <p>Permits you to generate a CVS file from a query result. The first parameter of the function must contain the result object from your query.
|
| 90 | Example:</p>
|
| 91 |
|
| 92 | <code>
|
| 93 | $this->load->dbexport();<br />
|
| 94 | <br />
|
| 95 | $query = $this->db->query("SELECT * FROM mytable");<br />
|
| 96 | <br />
|
| 97 | echo $this->dbexport->cvs_from_result($query);
|
| 98 | </code>
|
| 99 |
|
| 100 | <p>The second and third parameters allows you to
|
| 101 | set the delimiter and newline character. By default tabs are used as the delimiter and "\n" is used as a new line. Example:
|
| 102 |
|
| 103 | <code>
|
| 104 | $delimiter = ",";<br />
|
| 105 | $newline = "\r\n";<br />
|
| 106 | <br />
|
| 107 | echo $this->dbexport->cvs_from_result($query, $delimiter, $newline);
|
| 108 | </code>
|
| 109 |
|
| 110 | <p class="important"><strong>Important:</strong> This function will NOT write the CVS file for you. It simply creates the CVS layout.
|
| 111 | If you need to write the file use the <a href="../helpers/file_helper.html">File Helper</a>.</p>
|
| 112 |
|
| 113 |
|
| 114 |
|
| 115 | <h2>$this->dbexport->xml_from_result($db_result)</h2>
|
| 116 |
|
| 117 | <p>Permits you to generate an XML file from a query result. The first parameter expects a query result object, the second
|
| 118 | may contain an optional array of config parameters. Example:</p>
|
| 119 |
|
| 120 | <code>
|
| 121 | $this->load->dbexport();<br />
|
| 122 | <br />
|
| 123 | $query = $this->db->query("SELECT * FROM mytable");<br />
|
| 124 | <br />
|
| 125 | $config = array (<br />
|
| 126 | 'root' => 'root',<br />
|
| 127 | 'element' => 'element', <br />
|
| 128 | 'newline' => "\n", <br />
|
| 129 | ';tab' => "\t"<br />
|
| 130 | );<br />
|
| 131 | <br />
|
| 132 | echo $this->dbexport->cvs_from_result($query, $config);
|
| 133 | </code>
|
| 134 |
|
| 135 | <p class="important"><strong>Important:</strong> This function will NOT write the CVS file for you. It simply creates the CVS layout.
|
| 136 | If you need to write the file use the <a href="../helpers/file_helper.html">File Helper</a>.</p>
