如何在PHP搜索之前隐藏表格

标签： php mysql

这是我的代码。在搜索其显示整个表值之前。搜索过滤器工作正常。但默认情况下，我需要隐藏table。 HTML代码： 

 <form id="form1" name="form1" method="post" action="search.php">
<label for="from">From</label>
<input name="from" type="text" id="from" size="10" value="<?php echo $_REQUEST["from"]; ?>" />
<label for="to">to</label>
<input name="to" type="text" id="to" size="10" value="<?php echo $_REQUEST["to"]; ?>"/>
 <label>Name or Email:</label>
<input type="text" name="string" id="string" value="<?php echo stripcslashes($_REQUEST["string"]); ?>" />
<label>City</label>
<select name="city">
<option value="">--</option>
<?php
    $sql = "SELECT * FROM ".$SETTINGS["data_table"]." GROUP BY city ORDER BY city";
    $sql_result = mysql_query ($sql, $connection ) or die ('request "Could not execute SQL query" '.$sql);
    while ($row = mysql_fetch_assoc($sql_result)) {
        echo "<option value='".$row["city"]."'".($row["city"]==$_REQUEST["city"] ? " selected" : "").">".$row["city"]."</option>";
    }
?>
</select>
<input type="submit" name="button" id="button" value="Filter" />
  </label>
      </form>

PHP代码： 

<table width="700" border="1" cellspacing="0" cellpadding="4">
  <tr>
    <td width="90" bgcolor="#CCCCCC"><strong>From date</strong></td>
    <td width="95" bgcolor="#CCCCCC"><strong>To date</strong></td>
    <td width="159" bgcolor="#CCCCCC"><strong>Name</strong></td>
    <td width="191" bgcolor="#CCCCCC"><strong>Email</strong></td>
    <td width="113" bgcolor="#CCCCCC"><strong>City</strong></td>
  </tr>
<?php
if ($_REQUEST["string"]<>'') {
    $search_string = " AND (full_name LIKE '%".mysql_real_escape_string($_REQUEST["string"])."%' OR email LIKE '%".mysql_real_escape_string($_REQUEST["string"])."%')"; 
}
if ($_REQUEST["city"]<>'') {
    $search_city = " AND city='".mysql_real_escape_string($_REQUEST["city"])."'";   
}

if ($_REQUEST["from"]<>'' and $_REQUEST["to"]<>'') {
    $sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE from_date >= '".mysql_real_escape_string($_REQUEST["from"])."' AND to_date <= '".mysql_real_escape_string($_REQUEST["to"])."'".$search_string.$search_city;
} else if ($_REQUEST["from"]<>'') {
    $sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE from_date >= '".mysql_real_escape_string($_REQUEST["from"])."'".$search_string.$search_city;
} else if ($_REQUEST["to"]<>'') {
    $sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE to_date <= '".mysql_real_escape_string($_REQUEST["to"])."'".$search_string.$search_city;
} else {
    $sql = "SELECT * FROM ".$SETTINGS["data_table"]." WHERE id>0".$search_string.$search_city;
}

$sql_result = mysql_query ($sql, $connection ) or die ('request "Could not execute SQL query" '.$sql);
if (mysql_num_rows($sql_result)>0) {
    while ($row = mysql_fetch_assoc($sql_result)) {
?>
  <tr>
    <td><?php echo $row["from_date"]; ?></td>
    <td><?php echo $row["to_date"]; ?></td>
    <td><?php echo $row["full_name"]; ?></td>
    <td><?php echo $row["email"]; ?></td>
    <td><?php echo $row["city"]; ?></td>
  </tr>
<?php
    }
} else {
?>
<tr><td colspan="5">No results found.</td>
<?php   
}
?>
</table>

代码运行正常。在php和mysql中提交搜索按钮之前如何隐藏表格。如果有人知道，请回答我的问题。

我找到了解决方法。

我添加了

if(isset($_POST['button']))

在表格之前。因此，表格将在提交表单后显示。
