这将回显来自数据库的下拉值
<select name="PACKAGE_ID" id="PACKAGE_ID" ng-model="FormData.Phases" class="form-control" required>
<?php
$result=mysqli_query($conn, "select * from unifi WHERE STATUS!='DELETE' ORDER BY PACKAGE_NAME ASC");
while ($row=mysqli_fetch_assoc($result)) {
?>
<option name="UNIFI" value="<?php echo $row["PACKAGE_NAME"]; ?>">
<?php echo $row[ "PACKAGE_NAME"]; ?>
</option>
<?php } ?>
<?php $result=mysqli_query($conn, "select * from streamyx WHERE STATUS!='DELETE' ORDER BY PACKAGE_NAME ASC");
while ($row=mysqli_fetch_assoc($result)) {?>
<option name="STREAMYX" value="<?php echo $row["PACKAGE_NAME"]; ?>">
<?php echo $row[ "PACKAGE_NAME"]; ?>
</option>
<?php } ?>
<?php $result=mysqli_query($conn, "select * from webe WHERE STATUS!='DELETE' ORDER BY PACKAGE_NAME ASC");
while ($row=mysqli_fetch_assoc($result)) {?>
<option name="WEBE" value="<?php echo $row["PACKAGE_NAME"]; ?>">
<?php echo $row[ "PACKAGE_NAME"]; ?>
</option>
<?php } ?>
<?php $result=mysqli_query($conn, "select * from dome WHERE STATUS!='DELETE' ORDER BY PACKAGE_NAME ASC");
while ($row=mysqli_fetch_assoc($result)) {?>
<option name="WEBE" value="<?php echo $row["PACKAGE_NAME"]; ?>">
<?php echo $row[ "PACKAGE_NAME"]; ?>
</option>
<?php } ?>
下面是如何根据故障单ID
从数据库中获取值 $sql = "SELECT * FROM cusinfo WHERE TICKET_ID = '".$strid."' ";
$query = mysqli_query($conn,$sql);
$result=mysqli_fetch_array($query,MYSQLI_ASSOC);
我希望回显例如。<<< $result["PACKAGE_ID"]==$row[ "PACKAGE_NAME"] echo selected >>
答案 0 :(得分:1)
由于您在后续查询中多次使用$result
变量,因此您需要将$result["PACKAGE_CATEGORY"]
保留为新变量,如下所示:
$selected=$result["PACKAGE_CATEGORY"];
您可以编写如下的内联条件语句:
echo "<option name=\"WEBE\" value=\"{$row["PACKAGE_NAME"]}\"",($row[ "PACKAGE_NAME"]==$selected?" selected":""),">{$row["PACKAGE_NAME"]}</option>";
这意味着如果条件为真,则将回显selected
,如果为false,则将回显空字符串。
多行上的相同技术如下所示:
echo "<option name=\"WEBE\" value=\"{$row["PACKAGE_NAME"]}\"";
echo $row["PACKAGE_NAME"]==$selected?" selected":"";
echo ">{$row["PACKAGE_NAME"]}</option>";
如果您不想使用内联条件,则标准语法为:
echo "<option name=\"WEBE\" value=\"{$row["PACKAGE_NAME"]}\"";
if($row["PACKAGE_NAME"]==$selected){
echo " selected";
}
echo ">{$row["PACKAGE_NAME"]}</option>";
