¿Pueden varias entradas tener el mismo nombre?

Can multiple inputs have the same name?

Yes — each will only submit with their respective forms. If you have them in the same form, one will override the other and it is not valid.

You can have tables of the same name only if they are in separate databases, and you use the database name as a qualifier.

INSERT-SELECT-UNION query to insert multiple records Thus, we can use INSERT-SELECT-UNION query to insert data into multiple rows of the table. The SQL UNION query helps to select all the data that has been enclosed by the SELECT query through the INSERT statement.

MySQL Insert Multiple Rows

1. First, specify the name of table that you want to insert after the INSERT INTO keywords.
2. Second, specify a comma-separated column list inside parentheses after the table name.
3. Third, specify a comma-separated list of row data in the VALUES clause. Each element of the list represents a row.

A TEMPORARY table is visible only to the current session, and is dropped automatically when the session is closed. This means that two different sessions can use the same temporary table name without conflicting with each other or with an existing non-TEMPORARY table of the same name.

In the context of a relational database, a row—also called a tuple—represents a single, implicitly structured data item in a table. In simple terms, a database table can be thought of as consisting of rows and columns.

SQL Insert from Another Table If you have your data in another table and want to insert it into a new table, you can use an INSERT statement and a SELECT statement. This works in all database vendors. INSERT INTO customer (first_name, last_name) SELECT fname, lname FROM list_of_customers WHERE active = 1;

Simply connect to 1 database, insert new row, disconnect, connect to the other database, insert row into that one and disconnect. Or you can use $connect1 and $connect2 to refer to each of them separately and do the insertion parallely. And very important, you should write mysqli not mysql.

The INSERT INTO statement adds a new record to a table. INSERT INTO can contain values for some or all of its columns. INSERT INTO can be combined with a SELECT to insert a record.

If you add use a sequence and call the nextval value, then the same row will be used for each inserted row. If you have your data in another table and want to insert it into a new table, you can use an INSERT statement and a SELECT statement.

Hello readers, Below example will help you to “Get Multiple Parameters with same name from a URL in PHP”.

2. $query = explode(‘&’, $_SERVER[‘QUERY_STRING’]);
3. $params = array();
4. foreach( $query as $param )
5. {
6. list($name, $value) = explode(‘=’, $param, 2);
7. $params[urldecode($name)][] = urldecode($value);
8. }

You can assign the same value to multiple variables by using = consecutively. This is useful, for example, when initializing multiple variables to the same value. It is also possible to assign another value into one after assigning the same value.

Bottom line: you can’t have two things simultaneously with the same name, be it a function, an integer, or any other object in Python. Just use a different name. names in Python are typically identifiers for a specific type, more like naming a box which stores a variable/function/method or any object in Python.

The most direct way to determine if two values are not equal in Python is to use the != operator (Note: There should not be any space between ! and = ). The != operator returns True if the values on both sides of the operator are not equal to each other.

Identifiers are names given to different entities such as constants, variables, structures, functions, etc. Example: int amount; double totalbalance; In the above example, amount and totalbalance are identifiers and int, and double are keywords.

What Makes a Good Identifier? The identifier is unique — no two users will have the same identifier. The identifier is never reassigned to another user. The identifier is persistent — meaning that the same identifier will be delivered by the IdP to the SP each time a given person visits the SP’s site.

“Message”: “No HTTP resource was found that matches the request URI…” Yes, it’s possible to pass multiple POST parameters of course, but Web API expects you to use Model Binding for this – mapping the post parameters to a strongly typed .NET object, not to single parameters.

(NOTE: In this case, it would be important to name query key to some_name [], so that the resulting request vars would be registered as an array by PHP) there is no standard, but most frameworks support both, you can see for example for java spring that it accepts both here

Say, for example, I have five input on one page named “xyz” and I want to access them using PHP. Could I do something like: If so, that would make my life ten times easier, as I could send an indefinite amount of information through a form and get it processed by the server simply by looping through the array of items with the name “xyz”.

One of the features that doesn’t work out of the box – somewhat unexpectedly – is the ability to map POST form variables to simple parameters of a Web API method. For example imagine you have this form and you want to post this data to a Web API end point like this via AJAX:

The serializeArray() is an inbuilt method in jQuery which is used to create a JavaScript array of objects that is ready to be encoded as a JSON string. It operates on a jQuery collection of forms and/or form controls. JSON string is a text and can convert any JavaScript object into JSON, and send JSON to the server.

The serialize() function converts a storable representation of a value. To serialize data means to convert a value to a sequence of bits, so that it can be stored in a file, a memory buffer, or transmitted across a network.

Serialize() converts an array, given as its only parameter, into a normal string that you can save in a file, pass in a URL, etc. Unserialize() is the opposite of serialize() – it takes a serialize()d string and converts it back to an array.

Definition and Usage. The serializeArray() method creates an array of objects (name and value) by serializing form values. You can select one or more form elements (like input and/or text area), or the form element itself.

Data from file select elements is not serialized. Elements that do not contain a value attribute are represented with the empty string value. This method can act on a jQuery object that has selected individual form controls, such as , , and .

The .serializeArray () method uses the standard W3C rules for successful controls to determine which elements it should include; in particular the element cannot be disabled and must contain a name attribute. No submit button value is serialized since the form was not submitted using a button.
