我的Dropbox有以下代码;
<select name="Symptom" id="Symptomid" onchange="LSC(this.value)">
它的选择是;
<option value="<?php echo $row_RsSymptom['name']?>"><?php echo $row_RsSymptom['name']?></option>
完整的Html代码;

q未被挑选。如果我删除它运行的where语句并显示表。
请帮忙。

答案 0 :(得分：0)
由于我们无法看到PHP的其余部分，请立即尝试：
$sql1 = mysql_query("SELECT name,description , comments
FROM symptoms WHERE symptoms.name ='".$_GET['q']."'") or die(mysql_error());
