我正在尝试获取在文本区域中输入的网址的元标记,这有什么问题?
另外,我如何将元描述来自的URL与描述相结合?
<form method="get">
<textarea name="TAData">
</textarea>
<input type="submit" value="submit"/>
</form>
<div id="checkboxes">
<input type="checkbox" name="vehicle" value="PR" /> Show me the PR<br />
<input type="checkbox" name="vehicle" value="KW Tag" /> Show me the KW tag<br />
<input type="checkbox" name="vehicle" value="Title Tag" /> Show me the Title tag<br />
</div>
<div id="checkboxes">
<input type="checkbox" name="vehicle" value="1stH1" /> Show me the 1st H1<br />
<input type="checkbox" name="vehicle" value="2ndH1" /> Show me the 2nd H1 tag<br />
<input type="checkbox" name="vehicle" value="SeedKW" /> Show me Seed KW's<br />
</div>
<div id="nofloat"></div>
<?php
//make the array
$TAarray = explode("\n", strip_tags($_POST['TAData']));
var_dump($TAarray);
//loop through the array
foreach ($TAarray as $line) {
$line = htmlspecialchars(trim($line));
}
foreach ($TAarray as $url) {
// get the meta data for each url
$tags = get_meta_tags($url);
unset($tags["content-type"]);
unset($tags["page-type"]);
unset($tags["page-topic"]);
unset($tags["audience"]);
echo '<tr>';
foreach ($tags['description'] as $meta)
{
echo '<td>' . $meta . '</td>';
}
echo '</tr>';
}
?>
另外,有没有办法只包含元描述?
答案 0 :(得分:1)
1)您的表单被声明为GET,但您正在从$ _POST字段中读取值。
2)如果你只想提取“描述”元值,你不需要对标签进行迭代,你可以使用:
$description = $tags["description"]
