❶ php的select下拉列表取值無法存入資料庫
建議這樣調試,在帖子的最後一個語句($sql="insert into text1 values('$id')";)之後添加下面的三行:
echo "正在執行SQL: $sql<BR> \n";
if (mysql_query($sql)) echo "成功。";
else echo "失敗:".mysql_error();
這樣就會知道資料庫查詢執行是否成功,如果失敗還會顯示失敗的具體原因,這個原因是分析程序非常重要的因素。
❷ php中select下拉選框默認項的動態設置

<title>JS Selector</title>
<script type="text/javascript">
function createSelect(c){
var _inner = {
"nation" : ['漢族','蒙古族','彝族','侗族','哈薩克族',

}
var _array = c["array"] || _inner[c["type"]];
var _select = document.createElement("select");
for(var i=0; i < _array.length; i++){
_select.options[i] = new Option(_array[i], _array[i]);

return _select;
}
function loadRender(){
document.getElementById('field-nation').appendChild(
createSelect({type : "nation", selected : "漢族", name : "nation"})
);
document.getElementById('field-ecation').appendChild(
createSelect({type : "degree", selected : "本科", name : "ecation"})
);
}
</script>
</head>
<body onload="loadRender();">
<div id="field-nation"></div>
<div id="field-ecation"></div>

</html>
直接把變數傳到:
document.getElementById('field-nation').appendChild(
createSelect({type : "nation", selected : "<?=$nation?>", name : "nation"})
);
document.getElementById('field-ecation').appendChild(
createSelect({type : "degree", selected : "<?=$degree?>", name : "ecation"})
);
