| 59 | <h1>HTML Helper</h1> |
| 60 | |
| 61 | <p>The HTML Helper file contains functions that assist in working with HTML.</p> |
| 62 | |
| 63 | |
| 64 | <h2>Loading this Helper</h2> |
| 65 | |
| 66 | <p>This helper is loaded using the following code:</p> |
| 67 | <code>$this->load->helper('html');</code> |
| 68 | |
| 69 | <p>The following functions are available:</p> |
| 70 | |
| 71 | <h2>br()</h2> |
| 72 | <p>Generates line break tags (<br />) based on the number you submit. Example:</p> |
| 73 | <code>echo br(3);</code> |
| 74 | <p>The above would produce: <br /><br /><br /></p> |
| 75 | |
| 76 | <h2>heading()</h2> |
| 77 | <p>Lets you create HTML <h1> tags. The first parameter will contain the data, the |
| 78 | second the size of the heading. Example:</p> |
| 79 | <code>echo heading('Welcome!', 3);</code> |
| 80 | <p>The above would produce: <h3>Welcome!</h3></p> |
| 81 | <h2>img()</h2> |
| 82 | <p>Lets you create HTML <img /> tags. The first parameter contains the image source. Example:</p> |
| 83 | <code>echo img('images/picture.jpg');<br /> |
| 84 | // gives <img src="http://site.com/images/picture.jpg" /></code> |
| 85 | <p>There is an optional second parameter that is a TRUE/FALSE value that specifics if the src should have the page specified by $config['index_page'] added to the address it creates. Presumably, this would be if you were using a media controller.</p> |
| 86 | <p><code>echo img('images/picture.jpg', TRUE);<br /> |
| 87 | // gives <img src="http://site.com/index.php/images/picture.jpg" /></code></p> |
| 88 | <p>Additionally, an associative array can be passed to the img() function for complete control over all attributes and values.</p> |
| 89 | <p><code> $image_properties = array(<br /> |
| 90 | 'src' => 'images/picture.jpg',<br /> |
| 91 | 'alt' => 'Me, demonstrating how to eat 4 slices of pizza at one time',<br /> |
| 92 | 'class' => 'post_images',<br /> |
| 93 | 'width' => '200',<br /> |
| 94 | 'height' => '200',<br /> |
| 95 | 'title' => 'That was quite a night',<br /> |
| 96 | 'rel' => 'lightbox',<br /> |
| 97 | );<br /> |
| 98 | <br /> |
| 99 | img($image_properties);<br /> |
| 100 | // <img src="http://site.com/index.php/images/picture.jpg" alt="Me, demonstrating how to eat 4 slices of pizza at one time" class="post_images" width="200" height="200" title="That was quite a night" rel="lightbox" /></code></p> |
| 101 | <h2>link_tag()</h2> |
| 102 | <p>Lets you create HTML <link /> tags. This is useful for stylesheet links, as well as other links. The parameters are href, with optional rel, type, title, media and index_page. index_page is a TRUE/FALSE value that specifics if the href should have the page specified by $config['index_page'] added to the address it creates.<code> |
| 103 | echo link_tag('css/mystyles.css');<br /> |
| 104 | // gives <link href="http://site.com/css/mystyles.css" rel="stylesheet" type="text/css" /></code></p> |
| 105 | <p>Further examples:</p> |
| 106 | |
| 107 | <code> |
| 108 | echo link_tag('favicon.ico', 'shortcut icon', 'image/ico');<br /> |
| 109 | // <link href="http://site.com/favicon.ico" rel="shortcut icon" type="image/ico" /> |
| 110 | <br /> |
| 111 | <br /> |
| 112 | echo link('feed', 'alternate', 'application/rss+xml', 'My RSS Feed');<br /> |
| 113 | // <link href="http://site.com/feed" rel="alternate" type="application/rss+xml" title="My RSS Feed" /> </code> |
| 114 | <p>Additionally, an associative array can be passed to the link() function for complete control over all attributes and values.</p> |
| 115 | <p><code> |
| 116 | $link = array(<br /> |
| 117 | 'href' => 'css/printer.css',<br /> |
| 118 | 'rel' => 'stylesheet',<br /> |
| 119 | 'type' => 'text/css',<br /> |
| 120 | 'media' => 'print'<br /> |
| 121 | );<br /> |
| 122 | <br /> |
| 123 | echo link_tag($link);<br /> |
| 124 | // <link href="http://site.com/css/printer.css" rel="stylesheet" type="text/css" media="print" /></code></p> |
| 125 | |
| 126 | <h2>nbs()</h2> |
| 127 | <p>Generates non-breaking spaces (&nbsp;) based on the number you submit. Example:</p> |
| 128 | <code>echo nbs(3);</code> |
| 129 | <p>The above would produce: &nbsp;&nbsp;&nbsp;</p> |
| 130 | |
| 131 | <h2>ol() and ul()</h2> |
| 132 | |
| 133 | <p>Permits you to generate ordered or unordered HTML lists from simple or multi-dimensional arrays. Example:</p> |
| 134 | |
| 135 | <code> |
| 136 | $this->load->helper('html');<br /> |
| 137 | <br /> |
| 138 | $list = array(<br /> |
| 139 | 'red', <br /> |
| 140 | 'blue', <br /> |
| 141 | 'green',<br /> |
| 142 | 'yellow'<br /> |
| 143 | );<br /> |
| 144 | <br /> |
| 145 | $attributes = array(<br /> |
| 146 | 'class' => 'boldlist',<br /> |
| 147 | 'id' => 'mylist'<br /> |
| 148 | );<br /> |
| 149 | <br /> |
| 150 | echo ul($list, $attributes);<br /> |
| 151 | </code> |
| 152 | |
| 153 | <p>The above code will produce this:</p> |
| 154 | |
| 155 | <code> |
| 156 | <ul class="boldlist" id="mylist"><br /> |
| 157 | <li>red</li><br /> |
| 158 | <li>blue</li><br /> |
| 159 | <li>green</li><br /> |
| 160 | <li>yellow</li><br /> |
| 161 | </ul> |
| 162 | </code> |
| 163 | |
| 164 | <p>Here is a more complex example, using a multi-dimensional array:</p> |
| 165 | |
| 166 | <code> |
| 167 | $this->load->helper('html');<br /> |
| 168 | <br /> |
| 169 | $list = array(<br /> |
| 170 | 'colors' => array(<br /> |
| 171 | 'red',<br /> |
| 172 | 'blue',<br /> |
| 173 | 'green'<br /> |
| 174 | ),<br /> |
| 175 | 'shapes' => array(<br /> |
| 176 | 'round', <br /> |
| 177 | 'square',<br /> |
| 178 | 'circles' => array(<br /> |
| 179 | 'ellipse', <br /> |
| 180 | 'oval', <br /> |
| 181 | 'sphere'<br /> |
| 182 | )<br /> |
| 183 | ),<br /> |
| 184 | 'moods' => array(<br /> |
| 185 | 'happy', <br /> |
| 186 | 'upset' => array(<br /> |
| 187 | 'defeated' => array(<br /> |
| 188 | 'dejected',<br /> |
| 189 | 'disheartened',<br /> |
| 190 | 'depressed'<br /> |
| 191 | ),<br /> |
| 192 | 'annoyed',<br /> |
| 193 | 'cross',<br /> |
| 194 | 'angry'<br /> |
| 195 | )<br /> |
| 196 | )<br /> |
| 197 | );<br /> |
| 198 | <br /> |
| 199 | <br /> |
| 200 | echo ul($list);</code> |
| 201 | |
| 202 | <p>The above code will produce this:</p> |
| 203 | |
| 204 | <code> |
| 205 | <ul class="boldlist" id="mylist"><br /> |
| 206 | <li>colors<br /> |
| 207 | <ul><br /> |
| 208 | <li>red</li><br /> |
| 209 | <li>blue</li><br /> |
| 210 | <li>green</li><br /> |
| 211 | </ul><br /> |
| 212 | </li><br /> |
| 213 | <li>shapes<br /> |
| 214 | <ul><br /> |
| 215 | <li>round</li><br /> |
| 216 | <li>suare</li><br /> |
| 217 | <li>circles<br /> |
| 218 | <ul><br /> |
| 219 | <li>elipse</li><br /> |
| 220 | <li>oval</li><br /> |
| 221 | <li>sphere</li><br /> |
| 222 | </ul><br /> |
| 223 | </li><br /> |
| 224 | </ul><br /> |
| 225 | </li><br /> |
| 226 | <li>moods<br /> |
| 227 | <ul><br /> |
| 228 | <li>happy</li><br /> |
| 229 | <li>upset<br /> |
| 230 | <ul><br /> |
| 231 | <li>defeated<br /> |
| 232 | <ul><br /> |
| 233 | <li>dejected</li><br /> |
| 234 | <li>disheartened</li><br /> |
| 235 | <li>depressed</li><br /> |
| 236 | </ul><br /> |
| 237 | </li><br /> |
| 238 | <li>annoyed</li><br /> |
| 239 | <li>cross</li><br /> |
| 240 | <li>angry</li><br /> |
| 241 | </ul><br /> |
| 242 | </li><br /> |
| 243 | </ul><br /> |
| 244 | </li><br /> |
| 245 | </ul> |
| 246 | </code> |
| 247 | |
| 248 | |
| 249 | |
| 250 | <h2>meta()</h2> |
| 251 | |
| 252 | <p>Helps you generate meta tags. You can pass strings to the function, or simple arrays, or multidimensional ones. Examples:</p> |
| 253 | |
| 254 | <code> |
| 255 | echo meta('description', 'My Great site');<br /> |
| 256 | // Generates: <meta name="description" content="My Great Site" /><br /> |
| 257 | <br /><br /> |
| 258 | |
| 259 | echo meta('Content-type', 'text/html; charset=utf-8', 'equiv'); // Note the third parameter. Can be "equiv" or "name"<br /> |
| 260 | // Generates: <meta http-equiv="Content-type" content="text/html; charset=utf-8" /><br /> |
| 261 | |
| 262 | <br /><br /> |
| 263 | |
| 264 | echo meta(array('name' => 'robots', 'content' => 'no-cache'));<br /> |
| 265 | // Generates: <meta name="robots" content="no-cache" /><br /> |
| 266 | |
| 267 | <br /><br /> |
| 268 | |
| 269 | $meta = array(<br /> |
| 270 | array('name' => 'robots', 'content' => 'no-cache'),<br /> |
| 271 | array('name' => 'description', 'content' => 'My Great Site'),<br /> |
| 272 | array('name' => 'keywords', 'content' => 'love, passion, intrigue, deception'),<br /> |
| 273 | array('name' => 'robots', 'content' => 'no-cache'),<br /> |
| 274 | array('name' => 'Content-type', 'content' => 'text/html; charset=utf-8', 'type' => 'equiv')<br /> |
| 275 | );<br /> |
| 276 | <br /> |
| 277 | echo meta($meta); |
| 278 | <br /> |
| 279 | // Generates: <br /> |
| 280 | // <meta name="robots" content="no-cache" /><br /> |
| 281 | // <meta name="description" content="My Great Site" /><br /> |
| 282 | // <meta name="keywords" content="love, passion, intrigue, deception" /><br /> |
| 283 | // <meta name="robots" content="no-cache" /><br /> |
| 284 | // <meta http-equiv="Content-type" content="text/html; charset=utf-8" /> |
| 285 | </code> |
| 286 | |
| 287 | |
| 288 | <h2>doctype()</h2> |
| 289 | |
| 290 | <p>Helps you generate document type declarations, or DTD's. XHTML 1.0 Strict is used by default, but many doctypes are available.</p> |
| 291 | |
| 292 | <code> |
| 293 | echo docytype();<br /> |
| 294 | // <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><br /> |
| 295 | <br /> |
| 296 | echo doctype('html4-trans');<br /> |
| 297 | // <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> |
| 298 | </code> |
| 299 | |
