This plugin generates POST Title from POST content automatically. Sometimes, you forget to write the title or sometimes you don’t want to write the title. It will generate the title for you. Or you can select a statement from your post content to be a title for the post using shortcodes [agt][/agt].
How does it work? 
If you leave the title field empty, only then this plugin will work. 
There are two different ways, this plugin works: – 
* Firstly it will search the content to check whether you have used [agt][/agt]shortcode or not. If used, it will make the wrapped line as title. 
* If you haven’t used shortcode in your post, it will automatically pick first 30 characters from the post and will use them as post title.
Currently this plugin is tested with latest wordpress version 4.1, but it should work with other versions also.

Secondary Title is a simple, light-weight plugin that adds an alternative title to posts, pages, and/or <a href="https://codex.wordpress.org/Post_Types" rel="nofollow ugc">custom post types</a>, which can be displayed automatically, with a shortcode or by using PHP.
The plugin comes with an extra settings page, which allows you to customize the plugin according to your needs. You can change:
<ul>
<li><a href="https://codex.wordpress.org/Post_Types" rel="nofollow ugc">post types</a>, categories, and specific post IDs the secondary title will be 
shown on,</li>
<li>whether the secondary title should be automatically added to the standard title (Auto show),</li>
<li>the format both titles are being shown (only works when Auto show is activated),</li>
<li>the position where the secondary title input field should be displayed (above or below the standard title) within the admin interface (Classic Editor only),</li>
<li>whether the secondary title should only be displayed in the main post and not within widgets, etc.,</li>
<li>if the secondary title should be usable in <a href="https://codex.wordpress.org/Using_Permalinks" rel="nofollow ugc">permalinks</a>,</li>
<li>and even more.</li>
</ul>

Secondary Title

Earlier I marked it one star as everything had stopped working due to the error generated by the plugin. Turned out it was not due to the plugin but the malware attacked the admin area.

I am taking my words back and apologizing to the author of the plugin. As a developer myself I can feel his pain. Therefore I am reviewing my comment and updating it.

Once again, this is a great plugin for writing SEO based headings.

Works as expected


First off, this is great, it works very well, I'm super happy with it.



I did NOT however want to delve into making custom templates, what I wanted was to treat the subtitle field like the excerpt.  So I went to ChatGPT and said "make a wordpress plugin that replaces the content of the except with the content of a meta field"The only thing I had to change was the name of the field, which is _secondary_title.  I'd love to see this as an option in the plugin, the code is only about 10 lines.
