dropdownbox - how to set selected dropdown list in html -

this code dropdown list,plz guide me.

<div class = "form-inline">   <label class = "">situation</label>   <select selected="" name="sit" id="situ" class='form-control'style="margin-left: 30px; width: 145px;">     <option value="" >select</option>     <?     if ($situation != '') {     $revise = $situation;     }     foreach ($revise $row):     ?>     <option value="<?= $row['id']; ?>"><?= $row['situation']; ?></option>     <? endforeach; ?>   </select> </div> 

for item want selected dropdown list, add attribute selected.

eg.

<select>   <option value="0">0</option>   <option value="1" selected="selected">1</option>   <option value="2">2</option> </select> 

in case, 1 selected.

to value of dropdown after form submit, depends on method of form being post or get.

in example, i'm assuming it's post. <form method="post">

<div class = "form-inline">   <label class = "">situation</label>   <select selected="" name="sit" id="situ" class='form-control'style="margin-left: 30px; width: 145px;">     <option value="" >select</option>     <?     if (isset($_post['sit']))         $selected = $_post['sit'];     if ($situation != '') {     $revise = $situation;     }     foreach ($revise $row):         $selectedhtml = '';         if (isset($selected) && $row['id'] == $selected)             $selectedhtml = ' selected="selected"';     ?>     <option value="<?= $row['id']; ?>"<?= $selectedhtml; ?>><?= $row['situation']; ?></option>     <? endforeach; ?>   </select> </div> 

you can try this.

if (isset($_post['sit']))   $selected = $_post['sit']; 

what check if $_post['sit'] value found. if yes we'll make $selected, else we'll leave it.

$selectedhtml = ''; if (isset($selected) && $row['id'] == $selected)   $selectedhtml = ' selected="selected"'; 

and in foreach loop, first initialize $selectedhtml empty string. not add <option> unless got value changed.

we check if $selected defined or not , if is, check if current value of $row['id'] within foreach loop equal submitted value $selected. if so, set $selectedhtml add selected="selected" current <option>.
