需要在php上添加第二行和第三个定界符 [英] Need to add second line and third delimiter on php explode
问题描述
这结束了我的另一个已成功回答的问题:stackoverflow.com/questions/8597929/need-to-create-li-with-list-different-links-using-php-explode-method
所以现在我有了这个:
<?php
$separator1 = "\n";
$separator2 = ":";
$textarea = get_custom_field('my_custom_output');
$array = explode($separator1,$textarea);
$output = ''; // initialize the variable
foreach ($array as $item) {
list($item_text, $item_links) = explode($separator2, trim($item));
$output .= '<li class="link-class"><a title="' . $item_text . '" href="http://mywebsite.com/' . $item_links . '">' . $item_text . '</a></li>';
}
?>
<ul>
<?php print $output; ?>
</ul>
，并在定义为"my_custom_output"的文本区域中使用以下内容:
text1:text1-page-url
text2:new-text2-page
text3:different-page-text3
结果是
text1
text2
text3
已成功链接和设置样式. (我没有将它们链接，因为stackoverflow不允许我发布两个以上的链接，因为我只有3个代表).
因此，我的下一个也是最后一个想要完成的任务是:
text1
description 1
text2
description 2
text3
description 3
像以前一样链接text1等，但是不链接描述.
因此，我将在stackoverflow中尽力尝试一下.但是，我希望我需要一些帮助.走吧:
<?php
$separator1 = "\n";
$separator2 = ":";
$separator3 = ";";
$textarea = get_custom_field('my_custom_output');
$array = explode($separator1,$textarea);
$output = ''; // initialize the variable
foreach ($array as $item) {
list($item_text, $item_links) = explode($separator2, trim($item));
$output .= '<li class="link-class"><a title="' . $item_text . '" href="http://mywebsite.com/' . $item_links . '">' . $item_text . '</a><br /><span class="desc-class">' . $item_desc . '</span></li>';
}
?>
<ul>
<?php print $output; ?>
</ul>
，并在定义为"my_custom_output"的文本区域中使用以下内容:
text1:text1-page-url;Text1 Description
text2:new-text2-page;Description For Text2
text3:different-page-text3;A Text3 Description
我需要的输出是:
我不知道分号是否可以工作，但是我不能使用空格(\ s)，因为描述中有空格.我愿意接受建议.
================================================ =====
我最新的尝试:
<?php
$separator1 = "\n";
$separator2 = ":";
$separator3 = ";";
$textarea = get_custom_field('my_custom_output');
$array = explode($separator1,$textarea);
$output = ''; // initialize the variable
foreach ($array as $item) {
$itemarray = explode($separator2, trim($item));
$item_text = $itemarray[0];
list($item_links, $item_desc) = explode($separator3,$itemarray[1]);
$output .= '<li class="link-class"><a title="' . $item_text . '" href="http://mywebsite.com/' . $item_links . '">' . $item_text . '</a><br /><span class="desc-class">' . $item_desc . '</span></li>';
}
?>
<ul>
<?php print $output; ?>
</ul>
成功！！！ = D
不确定我是否足够了解(我不确定get_custom_field()能为您带来什么-无法作为常规的PHP函数找到)，但是当您爆炸一个包含多个定界符实例的项目时，您将获得多个数组.
所以:
$textarea = "text1:text1-page-url;Text1 Description";
$data = explode(':',$textarea);
// at this point $data[0] will contain "text1", while $data[1] contains text1-page-url;Text1 Description"
$descarray = explode(';',$data[1]);
// then $descarray[0] contains "text1-page-url" and $descarray[1] contains "Text1 Description" so you can echo this out however you like.
使用您的代码. 假设此时每个$ item是每一行，就像这样:
$item = "text1:text1-page-url;Text1 Description";
然后这将解决问题:
foreach ($array as $item) {
$itemarray = explode($separator2, trim($item));
$item_text = $itemarray[0];
list($item_links, $item_desc) = explode(';',$itemarray[1]);
$output .= '<li class="link-class"><a title="' . $item_text . '" href="http://mywebsite.com/' . $item_links . '">' . $item_text . '</a><br /><span class="desc-class">' . $item_desc . '</span></li>';
}
This is tailing off my other question which was successfully answered: stackoverflow.com/questions/8597929/need-to-create-li-with-list-of-different-links-using-php-explode-method
so now I have this:
<?php
$separator1 = "\n";
$separator2 = ":";
$textarea = get_custom_field('my_custom_output');
$array = explode($separator1,$textarea);
$output = ''; // initialize the variable
foreach ($array as $item) {
list($item_text, $item_links) = explode($separator2, trim($item));
$output .= '<li class="link-class"><a title="' . $item_text . '" href="http://mywebsite.com/' . $item_links . '">' . $item_text . '</a></li>';
}
?>
<ul>
<?php print $output; ?>
</ul>
and that, using the following in a textarea which is defined to "my_custom_output":
text1:text1-page-url
text2:new-text2-page
text3:different-page-text3
and the result is
text1
text2
text3
which are successfully linked and styled. (i didnt make them links because stackoverflow doesn't let me post more than two links because i only have 3 rep).
So my next and final desired task is to do this:
text1
description 1
text2
description 2
text3
description 3
where the text1 etc are linked like before but the descriptions are not linked.
So I will do my best, right here in stackoverflow, to try it. However, I expect I will need some help. Let's go:
<?php
$separator1 = "\n";
$separator2 = ":";
$separator3 = ";";
$textarea = get_custom_field('my_custom_output');
$array = explode($separator1,$textarea);
$output = ''; // initialize the variable
foreach ($array as $item) {
list($item_text, $item_links) = explode($separator2, trim($item));
$output .= '<li class="link-class"><a title="' . $item_text . '" href="http://mywebsite.com/' . $item_links . '">' . $item_text . '</a><br /><span class="desc-class">' . $item_desc . '</span></li>';
}
?>
<ul>
<?php print $output; ?>
</ul>
and to use the following in the textarea which is is defined to "my_custom_output":
text1:text1-page-url;Text1 Description
text2:new-text2-page;Description For Text2
text3:different-page-text3;A Text3 Description
and I need the output to be:
I don't know if semicolon will work, but I can't use a space (\s) because there are spaces in the description. I am open to suggestions.
====================================================
MY NEWEST TRY:
<?php
$separator1 = "\n";
$separator2 = ":";
$separator3 = ";";
$textarea = get_custom_field('my_custom_output');
$array = explode($separator1,$textarea);
$output = ''; // initialize the variable
foreach ($array as $item) {
$itemarray = explode($separator2, trim($item));
$item_text = $itemarray[0];
list($item_links, $item_desc) = explode($separator3,$itemarray[1]);
$output .= '<li class="link-class"><a title="' . $item_text . '" href="http://mywebsite.com/' . $item_links . '">' . $item_text . '</a><br /><span class="desc-class">' . $item_desc . '</span></li>';
}
?>
<ul>
<?php print $output; ?>
</ul>
IT WORKS!!! =D
Not sure if I understand this well enough (I'm not sure what get_custom_field() gets you - can't find that as a regular PHP function), but when you explode an item that has multiple instances of the delimiter, you'll get multiple arrays.
So:
$textarea = "text1:text1-page-url;Text1 Description";
$data = explode(':',$textarea);
// at this point $data[0] will contain "text1", while $data[1] contains text1-page-url;Text1 Description"
$descarray = explode(';',$data[1]);
// then $descarray[0] contains "text1-page-url" and $descarray[1] contains "Text1 Description" so you can echo this out however you like.
To work with your code.. Assume each $item is each row at this point, like this:
$item = "text1:text1-page-url;Text1 Description";
Then this will do the trick:
foreach ($array as $item) {
$itemarray = explode($separator2, trim($item));
$item_text = $itemarray[0];
list($item_links, $item_desc) = explode(';',$itemarray[1]);
$output .= '<li class="link-class"><a title="' . $item_text . '" href="http://mywebsite.com/' . $item_links . '">' . $item_text . '</a><br /><span class="desc-class">' . $item_desc . '</span></li>';
}
