我正在尝试构建一个允许从 pgsql 数据库生成自定义报告的页面。在 PHP 中，我声明了变量 $table、$datea 和 &datez... 然后我有一个 html 表单，用户可以在其中发布选定的表和这些变量的日期以供查询。但是，我收到一条错误消息(错误 500 页面不工作，无法处理此请求)。谁能提供一些建议？
$datea= $_POST["userDatea"];
$table= $_POST["userTable"];
$datez= $_POST["userDatez"];
if(isset($_POST['submit'])
// Create connection
$conn = pg_connect("host=xx.xx.xx.xx port=xxxx dbname=fpscdb001 user=xxx password=xxxxxxxxxxxxxx");
// Check connection
if (!$conn) {
echo "Did not connect.\n";
exit;
}
$result = pg_query($conn, "SELECT *
FROM
fpscdb001_ws_001.$table
WHERE
$table.created_on BETWEEN '$datea' AND '$datez' AND
$table.soft_delete_id = '0';");
Form:
<form method="post" id="report" action="custom.php">
<div class="formitem" style="max-width: 200px;">
<p style="font-color: white" style="font-weight: 800px">Select a Table:</p>
<p><select name="table" class="form-control" id="userTable">
<option value="dispatch_1">Dispatch</option>
<option value="normal_usb__a_t">Inventory</option>
<option value="incident">Real Estate</option>
<option value="tech_support2">Tech-Support</option>
</select></p>
</div>
<div class="formitem" style="max-width: 200px" style="margin-bottom: 20px">
<p>FROM DATE</p> <input type="DATE" class="textarea" id="userDatea" style="height: 30px; border-radius: 5px;"><br><br>
<p>TO DATE</p> <input type="DATE" class="textarea" id="userDatez" style="height: 30px; border-radius: 5px;"><br><br>
</div>
<div style="padding-bottom: 120px">
<input type="submit" class="btn btn-small greyBtn light submit" value="Submit" style="max-width: 200px; max-height: 125px">
</div>
</form>
最佳答案
试试这个。 请参阅我在代码中的评论。
<?php
// show error messages
ini_set('error_reporting', E_ALL);
ini_set("display_errors", 1);
$datea= $_POST["userDatea"];
$table= $_POST["userTable"];
$datez= $_POST["userDatez"];
// You need to do all of this if and only if this is a post request
// Also this method of detecting a post request is more consistent
if( !empty($_SERVER['REQUEST_METHOD']) && (strcasecmp($_SERVER['REQUEST_METHOD'], 'post')===0) ) {
// Create connection
$conn = pg_connect("host=xx.xx.xx.xx port=xxxx dbname=fpscdb001 user=xxx password=xxxxxxxxxxxxxx");
// Check connection
if (!$conn) {
echo "Did not connect.\n";
exit;
}
$result = pg_query($conn,
"SELECT *
FROM
fpscdb001_ws_001.$table
WHERE
$table.created_on BETWEEN '$datea' AND '$datez' AND
$table.soft_delete_id = '0';"
);
if (!$result) {
echo "Query failed\n";
exit;
}
exit('Success?');
}
?>
