unable to fetch value from html form to my python code

I'm unable to fetch information from my html form to my python code. I checked the code many times but there doesn't seem to be a problem. Please check my code and tell me what's wrong. Thank you.

@app.route("/search",methods=["POST","GET"]) 
def search1():                                #python code
    var=request.form.get("search2")
    sear=str(var)
    print(var,sear)
    return " "
<html>                      <!--html code-->
<head>
    <title>hi there</title>
</head>
<body>
    <h1 style="font-family:verdana; font-style:italic;">Welcome to the book sea !!!....</h1>
    <form action="{{ url_for('search1') }}" method="get" align:"center">
        <input type="text" name="search2" placeholder="enter details">
        <button>search</button>
    </form>
    
</body>

the problem was solved by reinstalling the flask app. Thanks for your effort.

Change the "get" in your HTML to "post". Because the way your Flask route is set up, it doesn't allow for a variable to be passed using a get request.

<form action="{{ url_for('search1') }}" method="get" align:"center">

to: 

<form action="{{ url_for('search1') }}" method="post" align:"center">

Also you might want to remove or edit align:"center" because it's not proper html. Add it in style="" attribute or remove it.

Also:

  1. Add a route to display the search form
  2. Check if the request is a post method since you're accepting both get and post
  3. You can use var=request.form["search2"] instead of var=request.form.get("search2")

===========================================

from flask import Flask, request, render_template

app = Flask(__name__)

@app.route("/")
def index():
    return render_template("search.html")

@app.route("/search",methods=["POST","GET"])
def search1():                                #python code
    if request.method == 'POST':
        var=request.form["search2"]
        sear=str(var)
        print(var,sear)
    return " "

if __name__ == "__main__":
    app.run(debug=True)

==== search.html .. should be placed in the templates folder of your project ===

<html>                      <!--html code-->
<head>
    <title>hi there</title>
</head>
<body>
<h1 style="font-family:verdana; font-style:italic;">Welcome to the book sea !!!....</h1>
<form action="{{ url_for('search1') }}" method="post">
    <input type="text" name="search2" placeholder="enter details">
    <button>search</button>
</form>

</body>

</html>
