admina3962762006-10-09 03:31:32 +0000[diff] [blame]66<p>The Table Class provides functions that enable you to auto-generate HTML tables from arrays or database result sets.</p>
admin9fd91c02006-10-09 03:30:36 +0000[diff] [blame]67
68<h2>Initializing the Class</h2>
69
admina3962762006-10-09 03:31:32 +0000[diff] [blame]70<p>Like most other classes in Code Igniter, the Table class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
admin9fd91c02006-10-09 03:30:36 +0000[diff] [blame]71
admina3962762006-10-09 03:31:32 +0000[diff] [blame]72<code>$this->load->library('table');</code>
admina1931ad2006-10-09 04:17:38 +0000[diff] [blame]73<p>Once loaded, the Table library object will be available using: <dfn>$this->table</dfn></p>
admin9fd91c02006-10-09 03:30:36 +0000[diff] [blame]74
75
admina1931ad2006-10-09 04:17:38 +0000[diff] [blame]76<h2>Examples</h2>
77
admine334c472006-10-21 19:44:22 +0000[diff] [blame]78<p>Here is an example showing how you can create a table from a multi-dimensional array.
79Note that the first array index will become the table heading (or you can set your own headings using the
admin2f0bac82006-10-09 17:36:45 +0000[diff] [blame]80<dfn>set_heading()</dfn> function described in the function reference below).</p>
admina1931ad2006-10-09 04:17:38 +0000[diff] [blame]81
82<code>
83$this->load->library('table');<br />
84<br />
85$data = array(<br />
86&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('Name', 'Color', 'Size'),<br />
87&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('Fred', 'Blue', 'Small'),<br />
88&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('Mary', 'Red', 'Large'),<br />
89&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('John', 'Green', 'Medium') <br />
90&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
91<br />
92echo $this->table->generate($data);
93</code>
94
admine334c472006-10-21 19:44:22 +0000[diff] [blame]95<p>Here is an example of a table created from a database query result. The table class will automatically generate the
admin2f0bac82006-10-09 17:36:45 +0000[diff] [blame]96headings based on the table names (or you can set your own headings using the <dfn>set_heading()</dfn> function described
97in the function reference below).</p>
admina1931ad2006-10-09 04:17:38 +0000[diff] [blame]98
99<code>
100$this->load->library('table');<br />
101<br />
102$query = $this->db->query("SELECT * FROM my_table");<br />
103<br />
104echo $this->table->generate($query);
105</code>
106
107
108<p>Here is an example showing how you might create a table using discreet parameters:</p>
109
110<code>
111$this->load->library('table');<br />
112<br />
113$this->table->set_heading('Name', 'Color', 'Size');<br />
114<br />
115$this->table->add_row('Fred', 'Blue', 'Small');<br />
116$this->table->add_row('Mary', 'Red', 'Large');<br />
117$this->table->add_row('John', 'Green', 'Medium');<br />
118<br />
119echo $this->table->generate();
120</code>
121
122<p>Here is the same example, except instead of individual parameters, arrays are used:
123
124<code>
125$this->load->library('table');<br />
126<br />
127$this->table->set_heading(array('Name', 'Color', 'Size'));<br />
128<br />
129$this->table->add_row(array('Fred', 'Blue', 'Small'));<br />
130$this->table->add_row(array('Mary', 'Red', 'Large'));<br />
131$this->table->add_row(array('John', 'Green', 'Medium'));<br />
132<br />
133echo $this->table->generate();
134</code>
135
136
137<h2>Changing the Look of Your Table</h2>
138
139<p>The Table Class permits you to set a table template with which you can specify the design of your layout. Here is the template
140prototype:</p>
141
142<code>
143$tmpl = array (<br />

admine334c472006-10-21 19:44:22 +0000[diff] [blame]168<p class="important"><strong>Note:</strong>&nbsp; You'll notice there are two sets of "row" blocks in the template. These permit you to create alternating row colors or design elements that alternate with each

183
184<h2>$this->table->generate()</h2>
185<p>Returns a string containing the generated table. Accepts an optional parameter which can be an array or a database result object.</p>
186
187<h2>$this->table->set_heading()</h2>
188
189<p>Permits you to set the table heading. You can submit an array or discreet params:</p>

192<code>$this->table->set_heading(array('Name', 'Color', 'Size'));</code>

202<h2>$this->table->make_columns()</h2>
203
204<p>This function takes a one-dimensional array as input and creates
205a multi-dimensional array with a depth equal to the number of
206columns desired. This allows a single array with many elements to be
207displayed in a table that has a fixed column count. Consider this example:</p>
