避免在php复选框中显示空行

时间：2014-07-05 10:01:30

标签： php html

我有html表单，其中有7个复选框。检查完所有方框后，结果都很好。虽然任何身体给出3或4个检查，但它显示结果，其间有空行。它看起来很不雅。任何机构都可以建议纠正代码。

复选框的HTML代码：

CONDITIONS: <br />
<input type="checkbox" name="c1" value="Invoice">Invoice <br />
<input type="checkbox" name="c2" value="LR copy">LR copy <br />
<input type="checkbox" name="c3" value="Test Reports">Test Reports<br />
<input type="checkbox" name="c4" value="Draft"> Draft<br />
<input type="checkbox" name="c5" value="Check-list">Check-List <br />
<input type="text" name="c6" placeholder=" Add any" maxlength="25" size="40"><br />
<input type="text" name="c7"  placeholder=" Add any clause"  maxlength="25" size="40">

上述复选框的php代码：

    <html>
<head>
<style type="text/css">

table { margin: 1em 0 0 0; border-collapse: collapse; }
td {margin: 5px 0 0 0;padding: .4em ;  border: 0px solid; height: 12px; }
tr td:first-child {font-weight: bold; width: 250px; color: black; height: 10px; font-size: 18px;}
tr td:last-child {width: 450px; color: blue;height: 10px; font-size: 18px; }

p {margin: 5px 0 0 20px; width: 700px; line height: 20px; text-align: justify; font-size:105%;
font-family: Arial, "Lucida Sans Unicode", Verdana, sans-serif;}

#trim {margin: 5px 0 0 20px; width: 700px; line height: 20px; text-align: center; font-size:150%;
font-family: Arial, "Lucida Sans Unicode", Verdana, sans-serif;}

.z{ margin: 5px 0 0 20px; width: 700px;}
.z1{ margin: 5px 0 0 20px; width: 700px;}

</style>

</head>
<body>

你总是在回应所有的线条。当某些值为空时，将只有空行（列表项）。所以你必须检查值是否存在。小例子：

    <?

    $html = '<p>CONDITIONS:</p><ul>';

    function echoRow(&$html, $val) {

      if (isset($val) && !empty($val))
        $html .= '<li>' . $val . '</li>';  
    }


    echoRow($c1);
    echoRow($c2);
    echoRow($c3);
    echoRow($c4);
    echoRow($c5);
    echoRow($c6);
    echoRow($c7);

    $html .= '</ul>';

    print($html);

?>

这是因为未选中复选框时，其值不会发送到服务器。例如，如果未选中C1，则不会发送$ _POST值。您可以做的是检查是否设置了每个复选框，并仅显示其值已退出的复选框。如果需要，可以显示未设置的复选框的替代消息。你可以做这样的事情

    $html="<ul>";

    if(isset($c1))
          $html.="<li>$c1</li>"
    else 
    {
     //do nothing or show alternative message 
     $html.="<li>Invoice not selected</li>"
    }

// do same for $c2....$c7
$html.="</ul>";
print($html);
