我有从MySQL数据库填充的texbox和下拉列表。我想从数据库中检索数据,并希望使用下拉列表选择下拉列表显示在文本框中,而无需刷新页面。这是我的代码,在此先感谢。
<select name="select1" class="form-control" id="dropdownlist1">
<option id="0">-- Select the Company --</option>
<?php
require("dbcon.php");
$getallcompanies = mysql_query("SELECT * FROM ifcandetails6");
while($viewallcompanies = mysql_fetch_array($getallcompanies)){
?>
<option id="<?php echo $viewallcompanies['tcuid']; ?>"><?php echo $viewallcompanies['tcname'] ?></option>
<?php
}
?>
</select>
输入文字框:
<input type="text" id="field1" value="<?php echo $viewallcompanies['tccontact']?>" disabled/>
最佳答案
像这样将事情分开:
<?php
require("dbcon.php");
$query = mysql_query("SELECT tcuid, tcname, tccontact FROM ifcandetails6");
while($row = mysql_fetch_array($query)){
$contacts[] = $row['tccontact'];
$companies[] = $row;
}
?>
<select name="select1" class="form-control" id="dropdownlist1">
<option id="0">-- Select the Company --</option>
<?php foreach($companies as $company) { ?>
<option id="<?= $company['tcuid']; ?>"><?= $company['tcname'] ?></option>
<?php } ?>
</select>
<?php foreach($contacts as $contact) { ?>
<input type="text" id="field1" value="<?= $contact['tccontact']?>"/>
<?php } ?>
