I'm currently working on the commerce project for CS50W. I'm working on the page to create a listing and i've set up my form. However for some reason the code I'm using to display the category is making the submit button disappear. I've verified that if I remove the code for the category specifically the button is present. Do you see anything that is wrong with my code that may be the problem?

{% extends "auctions/layout.html" %}

{% block body %}
    <h2>Create New Listing</h2>

    <form action="{% url 'create_listing' %}" method="POST">
        {% csrf_token %}
        <div class="form-group">
            <label for="title">Title</label>
            <input type="text" name="title" class"form-control" id="title" placeholder="Enter Title">
        <div class="form-group">
            <label for="description">Description</label>
            <input type="text" name="description" class"form-control" id="description" placeholder="Enter Description">
        <div class="form-group">
            <label for="price">Price</label>
            <input type="number" name="price" class"form-control" id="price" placeholder="Enter Price">
        <div class="form-group">
            <label for="imageurl">Image URL</label>
            <input type="text" name="imageurl" class"form-control" id="imageurl" placeholder="Enter Image URL">
        <div class="form-group">
            <label for="category">Choose a category:</label>
            <select name="category" id="category">
                {% for cat in categories %}
                    <option>{{ cat }}</option>
                {% endfor %}
        <button type="submit" class="btn btn-primary">Create New Listing</button>
{% endblock %}

At least one problem is the <select> element is not closed (ie </select>).

Consider validating the html as with Nu HTML Checker. An easy way is right-click on the page and "View Source" (or whatever your browser calls it), select and copy, then paste the code into the text area.

  • That was for sure the problem. Thank you for the tip with the HTML checker!! Commented Jan 13, 2023 at 3:08
