Question

I need some help with echoing a <img> tag with attributes like title, rel, and class.

I have made it this far, when I'm echoing a filename from a db to search in a catalogue to find it. But I'm not sure how to write some attributes to it since I'm going to display it with Pirobox.

This is what i got working:

echo '<a href="uploads/'.$row['bildnamn'].'">';
echo '<img src="uploads/'.$row['thumb_bildnamn'].'">';
echo '</a>';

But I also need these attributes for the <A> tag which makes the image large.

rel="gallery"  class="pirobox_gall" title="$row['uploaded']" . " " . "$row['user']";

What I don't get to work is how to get that line together with:

echo '<a href="uploads/'.$row['bildnamn'].'">';

Answer 1

你应该能够连接echo '<a href="uploads/' . $row['bildnamn'] . '" rel="gallery" class="pirobox_gall" title="' . $row['uploaded'] . ' ' . $row['user'] . '">'; echo '<img src="uploads/' . $row['thumb_bildnamn'] . '">'; echo '</a>';标签中的所有内容，如下所示：

title="' . $row['uploaded'] . ' ' . $row['user'] . '"

我插入了空格来帮助强调PHP连接的位置。在您的情况下，单引号开始/结束PHP的字符串;双引号被忽略并进入HTML。所以这一部分：

uploaded

会将标题设为user列的值，然后是空格，然后是a列的值。然后，只需使用>结束C:\Sites\scheduleio>rails s => Booting WEBrick => Rails 4.2.5.1 application starting in development on http://localhost:3000 => Run `rails server -h` for more startup options => Ctrl-C to shutdown server C:/Sites/scheduleio/config/initializers/ssl_configuration.rb:5: warning: already initialized constant OpenSSL::SSL::VERIFY_PEER Exiting代码。

Answer 2

你可以继续连接字符串

echo '<a href="uploads/'.$row['bildnamn'].'"'. 'rel="gallery"  class="pirobox_gall" title="'.$row['uploaded'].' '.$row['user'].'">';

Answer 3

试试这个：

echo '<a href="uploads/' . $row['bildnamn'] . '" rel="gallery"  class="pirobox_gall" title="' . $row['uploaded'] . ' ' . $row['user'] . '">';
echo '<img src="uploads/' . $row['thumb_bildnamn'] . '">';
echo '</a>';

Answer 4

您可以使用字符串连接执行此操作，如下所示：

            for(String token : tokens)
            {
                att[i] = token;
                i++;
                //Print all tokens
               // System.out.println(token);

                System.out.println(att[1]);
                break; // <---- ***take this out***
            }

PHP回显<img/> / <a> with attributes
