在新搜索中,我不希望它重置为星期一。我希望它能够追踪我的
中的内容$dag = $_GET["vdag"];
我想我已经接近了,但我无法找到我所遗漏的东西。有什么建议吗?
<form class="form-horizontal" method="get">
<div class="control-group">
<div class="controls form-inline"
<label for="inputValue">Choose day</label>
<select class="form-control" id="sel1" name="vdag">
<option value="1" <?= ($dag === 1 ? 'selected="selected"' : '')?>>Monday</option>
<option value="2" <?= ($dag === 2 ? 'selected="selected"' : '')?>>Tuesday</option>
<option value="3" <?= ($dag === 3 ? 'selected="selected"' : '')?>>Wednesday</option>
<option value="4" <?= ($dag === 4 ? 'selected="selected"' : '')?>>Thursday</option>
<option value="5" <?= ($dag === 5 ? 'selected="selected"' : '')?>>Friday</option>
</select>
<button type="submit" class="btn btn-default" value="Search">
<i class="glyphicon glyphicon-search"></i> Search
</button>
</div>
</div>
</form>
<?php
$dag = $_GET["vdag"]; <------ Here I get my number , 1 to 5
<!-- And more php code!-->
很抱歉,如果我不清楚。

使用此工作代码
<?php
if (isset($_GET["vdag"])) {
$dag = $_GET["vdag"];
} else {
$dag = 1;
}
?>
<form class="form-horizontal" method="get">
<div class="control-group">
<div class="controls form-inline"
<label for="inputValue">Choose day</label>
<select class="form-control" id="sel1" name="vdag">
<option value="1" <?= ($dag == 1 ? 'selected="selected"' : '') ?>>Monday</option>
<option value="2" <?= ($dag == 2 ? 'selected="selected"' : '') ?>>Tuesday</option>
<option value="3" <?= ($dag == 3 ? 'selected="selected"' : '') ?>>Wednesday</option>
<option value="4" <?= ($dag == 4 ? 'selected="selected"' : '') ?>>Thursday</option>
<option value="5" <?= ($dag == 5 ? 'selected="selected"' : '') ?>>Friday</option>
</select>
<button type="submit" class="btn btn-default" value="Search">
<i class="glyphicon glyphicon-search"></i> Search
</button>
