note 84278 added to function.array

The following function (similar to one above) will render an array as a series of HTML select options (i.e. "<option>...</option>"). The problem with the one before is that there was no way to handle <optgroup>, so this function solves that issue. function arrayToSelect($option, $selected = '', $optgroup = NULL) { $returnStatement = ''; if ($selected == '') { $returnStatement .= '<option value="" selected="selected">Select one...</option>'; } if (isset($optgroup)) { foreach ($optgroup as $optgroupKey => $optgroupValue) { $returnStatement .= '<optgroup label="' . $optgroupValue . '">'; foreach ($option[$optgroupKey] as $optionKey => $optionValue) { if ($optionKey == $selected) { $returnStatement .= '<option selected="selected" value="' . $optionKey . '">' . $optionValue . '</option>'; } else { $returnStatement .= '<option value="' . $optionKey . '">' . $optionValue . '</option>'; } } $returnStatement .= '</optgroup>'; } } else { foreach ($option as $key => $value) { if ($key == $selected) { $returnStatement .= '<option selected="selected" value="' . $key . '">' . $value . '</option>'; } else { $returnStatement .= '<option value="' . $key . '">' . $value . '</option>'; } } } return $returnStatement; } So, for example, I needed to render a list of states/provinces for various countries in a select field, and I wanted to use each country name as an <optgroup> label. So, with this function, if only a single array is passed to the function (i.e. "arrayToSelect($stateList)") then it will simply spit out a bunch of "<option>" elements. On the other hand, if two arrays are passed to it, the second array becomes a "key" for translating the first array. Here's a further example: $countryList = array( 'CA' => 'Canada', 'US' => 'United States'); $stateList['CA'] = array( 'AB' => 'Alberta', 'BC' => 'British Columbia', 'AB' => 'Alberta', 'BC' => 'British Columbia', 'MB' => 'Manitoba', 'NB' => 'New Brunswick', 'NL' => 'Newfoundland/Labrador', 'NS' => 'Nova Scotia', 'NT' => 'Northwest Territories', 'NU' => 'Nunavut', 'ON' => 'Ontario', 'PE' => 'Prince Edward Island', 'QC' => 'Quebec', 'SK' => 'Saskatchewan', 'YT' => 'Yukon'); $stateList['US'] = array( 'AL' => 'Alabama', 'AK' => 'Alaska', 'AZ' => 'Arizona', 'AR' => 'Arkansas', 'CA' => 'California', 'CO' => 'Colorado', 'CT' => 'Connecticut', 'DE' => 'Delaware', 'DC' => 'District of Columbia', 'FL' => 'Florida', 'GA' => 'Georgia', 'HI' => 'Hawaii', 'ID' => 'Idaho', 'IL' => 'Illinois', 'IN' => 'Indiana', 'IA' => 'Iowa', 'KS' => 'Kansas', 'KY' => 'Kentucky', 'LA' => 'Louisiana', 'ME' => 'Maine', 'MD' => 'Maryland', 'MA' => 'Massachusetts', 'MI' => 'Michigan', 'MN' => 'Minnesota', 'MS' => 'Mississippi', 'MO' => 'Missouri', 'MT' => 'Montana', 'NE' => 'Nebraska', 'NV' => 'Nevada', 'NH' => 'New Hampshire', 'NJ' => 'New Jersey', 'NM' => 'New Mexico', 'NY' => 'New York', 'NC' => 'North Carolina', 'ND' => 'North Dakota', 'OH' => 'Ohio', 'OK' => 'Oklahoma', 'OR' => 'Oregon', 'PA' => 'Pennsylvania', 'RI' => 'Rhode Island', 'SC' => 'South Carolina', 'SD' => 'South Dakota', 'TN' => 'Tennessee', 'TX' => 'Texas', 'UT' => 'Utah', 'VT' => 'Vermont', 'VA' => 'Virginia', 'WA' => 'Washington', 'WV' => 'West Virginia', 'WI' => 'Wisconsin', 'WY' => 'Wyoming'); ... <select name="state" id="state"><?php echo arrayToSelect($stateList,'',$countryList) ?></select> <select name="country" id="country"><?php echo arrayToSelect($countryList,'US') ?></select> ---- Server IP: 64.71.164.2 Probable Submitter: 140.239.17.68 ---- Manual Page -- http://www.php.net/manual/en/function.array.php Edit -- https://master.php.net/note/edit/84278 Del: integrated -- https://master.php.net/note/delete/84278/integrated Del: useless -- https://master.php.net/note/delete/84278/useless Del: bad code -- https://master.php.net/note/delete/84278/bad+code Del: spam -- https://master.php.net/note/delete/84278/spam Del: non-english -- https://master.php.net/note/delete/84278/non-english Del: in docs -- https://master.php.net/note/delete/84278/in+docs Del: other reasons-- https://master.php.net/note/delete/84278 Reject -- https://master.php.net/note/reject/84278 Search -- https://master.php.net/manage/user-notes.php
