联系表单7自定义占位符文本

Question

I have a contact form on every post. I am trying to display a different placeholder text on subject field on every post, where subject field placeholder text should be equal to the post title.

So this is current contact form tag:

[text text-900 placeholder "Subject"]

I tried replacing Subject with

<script>
 $("input").val("<?php echo $post; ?>");
</script>

but it hasn't worked.

Please help me solve this problem :)

Answer 1

Try this

jQuery('.wpcf7-form input[type=text]').attr("placeholder", "Your Post Title")

Complete PHP Code is below. Tested.

<script type="text/javascript">
    jQuery('.wpcf7-form input[type=text]').attr("placeholder", "<?php the_title(); ?>");
</script>
