title: woocommerce shop page, how to add custom price via "add to cart" button
body: <p>I can add a text box on the product page, which allows the user enter a custom price and the product is added to the cart with the custom price fine.</p>
  <p>My question is how do I do the same thing on the shop page?<br>
  I want to add a text box for each item on the shop page and allow users to enter a custom price.<br>
  On the shop page, I can add the text box for user to enter a custom price, but how do I transfer that price to the cart when user presses on the &quot;Add to cart&quot; button??</p>
  <p>The issue is that the button on the shop page is an href tag and its not an actual form submit.</p>
  <p>I've tried the woocommerce &quot;woocommerce_add_to_cart_validation&quot; hook but that doesn't work b/c by the time it gets here, I've lost the data from the shop page.<br>
  Is there a different hook for the shop page's &quot;add to cart&quot; button?<br>
  Is there a hook to save my information from shop page to the session?<br>
  If I have to change woocommerce page, which page should it be?</p>
  <p>Thanks in advance.</p>
