我创建了一个搜索表单,允许用户在打包数据库中搜索结果。我最近遇到了以三行为单位打印结果的问题,因为所有结果都是在下面打印一个,每个都是。我设法得到了修复,现在结果是三行,除了现在,有随机的间隙,一行或两行只有一个结果,但结果将继续下一行3.我似乎无法确定为什么这是随机发生的。
似乎没有任何模式,它会根据用户搜索的内容而有所不同。
这是PHP代码:
<?php
$con = mysql_connect ("localhost", "horizon1", "");
mysql_select_db ("horizon1_delyn", $con);
if (!$con)
{
die ("Could not connect: " . mysql_error());
}
$descrip = mysql_real_escape_string($_POST['descrip']);
$depth = mysql_real_escape_string($_POST['depth']);
$varWidth = mysql_real_escape_string($_POST['traywidth']);
$varHeight= mysql_real_escape_string($_POST['trayheight']);
$varRange = mysql_real_escape_string($_POST['trayrange']);
$varType = mysql_real_escape_string($_POST['traytype']);
$varShape = mysql_real_escape_string($_POST['trayshape']);
$varImage = mysql_real_escape_string($_POST['imagename']);
if (isset($varHeight) && !empty($varHeight)) {
$low = ($varHeight."00");
$high = ($varHeight."99");
} else {
$low = ("000");
$high = ("999");
}
if (isset($varWidth) && !empty($varWidth)) {
$min = ($varWidth."00");
$max = ($varWidth."99");
} else {
$min = ("000");
$max = ("999");
}
$sql = "SELECT * FROM range WHERE
description LIKE '%".$descrip."%'
AND trayrange LIKE '%".$varRange."%'
AND traytype LIKE '%".$varType."%'
AND trayshape LIKE '%".$varShape."%'
AND traywidth BETWEEN '".$min."' AND '".$max."'
AND trayheight BETWEEN '".$low."' AND '".$high."' ";
$r_query = mysql_query($sql);
$count = 0;
while ($row = mysql_fetch_array($r_query))
{
$t = $count%1;
echo ($t==4) ? '<div id="results">' : '<div id="results" style="float:left">';
echo '<p class="image">
<img src=" '. $row['imagename'] . '" width="150" length="80">
</p>';
echo '<div id="table">
<br /><strong> Tool Code: </strong> '. $row['toolcode'];
echo '<br /><strong> Description:</strong> '. $row['description'];
echo '<br /><strong> Tray range: </strong> '. $row['trayrange'];
echo '<br /><strong> Tray type: </strong> '. $row['traytype'];
echo '<br /><strong> Tray size: </strong> '. $row['traysize'];
echo '<br /><strong> Tray shape: </strong> '. $row['trayshape'] . '</div>' . '<br />';
echo '<a href="http://www.delynpackaging.co.uk/contact.htm">Enquiry Page</a> <br />' .
'<a href="http://176.67.171.11/range-test/rangetest.php">Back to Search</a>';
echo '</div>' . '</div>';
$count++;
}
if (mysql_num_rows($r_query) <= 0){
echo 'No results match your search, please try again';
}
?>
有人能看出为什么会这样吗?
答案 0 :(得分:0)
它可能取决于盒子的宽度,当它们不适合行时它们会包裹。 还$ t = $ count%1;看起来不寻常,应该是$ t = $ count%3;然后条件应为:( $ count&gt; 0&amp;&amp; $ t == 0)
