WEBVTT 00:00.650 --> 00:03.890 I will call you back again to another video lecture in PHP. 00:04.040 --> 00:09.860 In this video lecture, let's go ahead and learn how to accept input from a user in PHP. 00:16.940 --> 00:17.420 All right. 00:17.420 --> 00:20.960 So we know that PHP is a server side scripting language. 00:20.990 --> 00:28.040 Therefore it needs the client side scripting language like HTML to be able to accept input from a user. 00:28.280 --> 00:35.000 So what means is that you're going to create a HTML form where users can be able to input their username 00:35.000 --> 00:42.770 or password and so on, and then they can be able to collect these and pass in that to PHP, which is 00:42.800 --> 00:45.620 a server side scripting language, and move from there. 00:45.620 --> 00:48.020 They can move that to the database. 00:48.350 --> 00:56.630 So for us to be able to accept input from a user in PHP, it means we're going to write a small HTML 00:56.630 --> 01:03.380 code where we can be able to just create a form, because we're going to use that form to impute the 01:03.380 --> 01:04.220 user details. 01:04.250 --> 01:05.870 Let's go ahead and create a form. 01:05.900 --> 01:11.000 I'll go ahead and say form and I'll close this form. 01:12.710 --> 01:13.160 All right. 01:13.190 --> 01:22.940 Now I'm going to go right in here and give an action which is communicating with my PHP code. 01:22.970 --> 01:24.890 Let's go ahead and say action. 01:24.890 --> 01:31.910 So inside this action I'm going to tell the form, the PHP file that is going to act on the form that 01:31.910 --> 01:32.720 I'm creating. 01:32.720 --> 01:36.050 So in this case we are working on sites dot PHP. 01:36.080 --> 01:38.630 So I will say site dot PHP. 01:38.660 --> 01:44.030 That is the PHP file that is going to act on this particular form that I'm creating right now. 01:44.060 --> 01:49.790 And the word I want is to get the, uh, information from this form. 01:49.790 --> 01:51.410 So I'm going to create a method. 01:51.440 --> 01:56.570 The method is going to be a Get method because I want to get information. 01:56.570 --> 01:59.960 Therefore you are going to use a Get method. 02:00.380 --> 02:08.820 Now if we be able to give this for an action to act on this, which is the site dot PHP and they're 02:08.820 --> 02:10.200 using the method gate. 02:10.290 --> 02:13.350 Go ahead and create a simple form right in there. 02:13.350 --> 02:14.820 That is the input. 02:14.820 --> 02:16.680 So I want users to input. 02:16.680 --> 02:23.610 And the type of input I want right in here is going to be a text, because I just want you to input 02:23.610 --> 02:24.480 your username. 02:24.480 --> 02:29.730 Now I'll go ahead and say a name is going to be just username. 02:31.980 --> 02:32.400 All right. 02:32.430 --> 02:35.850 Go ahead and close this input tag. 02:35.880 --> 02:43.710 Now whenever a user inputs his or her name you're going to need a submit button to submit that input. 02:43.740 --> 02:47.880 Therefore you're going to create an A submit button. 02:47.880 --> 02:54.960 So another input tag and this time around is going to be a submit. 02:54.990 --> 02:56.940 Go ahead and create this input tag. 02:56.970 --> 02:59.550 Now let's go ahead and refresh this I check it out. 02:59.550 --> 03:05.450 So right now we have our form and we have the submit button. 03:05.480 --> 03:10.550 Now, if I go ahead and say that my name is George, and if I had to submit these, you can see that 03:10.550 --> 03:11.690 nothing happens. 03:11.720 --> 03:13.460 We are not able to see anything. 03:13.460 --> 03:16.550 I just submitted these and it went into the tint area. 03:16.580 --> 03:20.210 I need to submit these using the PHP file. 03:20.240 --> 03:28.040 Now I have to go back to my PHP right here just below here, and I'm going to type PHP to echo out, 03:28.040 --> 03:30.950 voice out, whatever that I input inside that form. 03:30.950 --> 03:32.870 So let's go ahead and say echo. 03:32.870 --> 03:39.440 And then we'll go ahead and use the dollar sign underscore get because we are using the Get method right 03:39.440 --> 03:39.920 in here. 03:39.920 --> 03:44.030 And now I'm go ahead and input the name which is the user name. 03:44.030 --> 03:48.080 So whatever name you input right in here is what I'm going to put down here. 03:48.080 --> 03:52.580 So I'll go ahead and say echo add the username I'll go ahead and save this. 03:52.640 --> 03:54.950 Now go ahead and refresh this again. 03:54.950 --> 03:59.180 And you see that the George I input before has been printed out. 04:00.110 --> 04:00.710 All right. 04:00.740 --> 04:02.450 Now let's go ahead and input another one. 04:02.450 --> 04:06.820 So I'm going to say Steve and go ahead and submit this now. 04:06.850 --> 04:08.980 Steve is now a cut out. 04:09.850 --> 04:12.790 So I basically get told to actually do this. 04:12.820 --> 04:13.600 You understand. 04:13.600 --> 04:14.530 So whatever. 04:14.650 --> 04:20.440 Whenever a user puts them right in there I'll go ahead and be able to voice that out. 04:20.440 --> 04:26.560 You can see that my PHP is now communicating with the, uh, the form I created. 04:26.590 --> 04:29.140 Now let's go ahead and put a small prompt right in here. 04:29.170 --> 04:33.610 So I'm going to say name and go ahead and save this refresh. 04:33.640 --> 04:34.570 And you can see name. 04:34.570 --> 04:37.030 So we call this know what the form is doing. 04:37.030 --> 04:44.500 So go ahead and say um this is uh George Steve and click on submit I have George Steve printed out. 04:45.010 --> 04:50.020 So if you want to input something like a name let's go ahead and say what are the name. 04:50.050 --> 04:51.970 Go ahead and put a break tag right in here. 04:51.970 --> 04:58.360 And I create a new c h I'm going to say what to add H. 04:58.390 --> 04:59.260 You understand. 04:59.260 --> 05:01.510 So go ahead and say input. 05:01.510 --> 05:05.620 And the type is going to be numbers. 05:06.070 --> 05:06.670 You understand. 05:06.700 --> 05:11.520 It's is known to be a text because we are dealing with numbers right now, so we'll go ahead and give 05:11.520 --> 05:12.360 it a name. 05:12.390 --> 05:18.570 Always give a name and whatever your inputs here, name, whatever you insert inside that name is what 05:18.570 --> 05:19.170 it's going to give. 05:19.380 --> 05:19.680 PHP. 05:19.710 --> 05:26.040 So if I put H or anything inside there, I'm going to let PHP know that this is what I'm working on. 05:26.070 --> 05:26.790 You understand. 05:26.790 --> 05:36.930 So go ahead and close that and I'll go right inside PHP and say echo and uh dollar underscore get. 05:36.930 --> 05:39.900 And then you go ahead and put in H. 05:39.930 --> 05:43.050 Save this and let's refresh this and check it out. 05:43.050 --> 05:48.030 So it says we have a syntax error right in here. 05:48.030 --> 05:52.860 So what actually happens right here is that I just want to echo this out. 05:52.890 --> 05:54.990 Go ahead and copy this. 05:55.470 --> 05:59.460 So I want this to be another stove right in here. 05:59.490 --> 06:05.190 Then go ahead and say so save this right now refresh this page. 06:05.190 --> 06:09.050 And uh we have name we have age. 06:09.050 --> 06:19.880 So if I go ahead and say name is hello and age is 20 and click on submit, we have hello 20. 06:21.200 --> 06:22.010 So you can see that. 06:22.010 --> 06:23.780 So we have hello 20. 06:24.470 --> 06:29.420 So I have two PHP uh tags right in here. 06:29.450 --> 06:34.820 If first one is echoing the username the second one is echoing the age. 06:34.850 --> 06:37.520 As you can see, our form is actually working fine. 06:37.700 --> 06:40.940 So let me say I want the 20 to be below. 06:40.940 --> 06:46.640 Go right in here after this PHP five and see I create a break tag. 06:46.640 --> 06:49.190 And let's go ahead and refresh this. 06:49.190 --> 06:51.590 And you can see that 20 has gone below. 06:52.340 --> 06:56.270 Now you can go ahead and make these customized a little. 06:56.300 --> 07:04.280 Let me say I want this guy and see your name is okay. 07:04.310 --> 07:05.720 Your name is. 07:06.230 --> 07:12.430 And uh, the second one Your age is 70s. 07:12.430 --> 07:14.140 And let's refresh this and check it out. 07:14.140 --> 07:15.460 So your name is hello. 07:15.490 --> 07:16.720 Your age is 20. 07:16.720 --> 07:22.570 So your name is George and your age is 24. 07:22.570 --> 07:23.830 So I check it out. 07:23.860 --> 07:25.390 Your name is George. 07:25.390 --> 07:26.920 Your age is 24. 07:26.950 --> 07:28.600 You can be able to see that right in here. 07:29.170 --> 07:33.040 So this is a way of accepting input from a user is in PHP. 07:33.130 --> 07:40.810 And for every form you create in HTML, you can see that we can actually use PHP to get the inputs from 07:40.810 --> 07:41.290 the user. 07:41.290 --> 07:44.350 And you can now move those inputs to our database. 07:44.470 --> 07:46.750 Right now we are not talking about database. 07:46.750 --> 07:51.820 That is why the input is just displayed on the screen, because you don't need to put this input on 07:51.820 --> 07:52.390 your screen. 07:52.390 --> 07:57.610 So when we talk about database then we'll go ahead and learn how to take this input and move them to 07:57.640 --> 07:58.300 the database. 07:58.300 --> 07:59.830 So for now practice with this. 07:59.860 --> 08:00.490 Check it out. 08:00.490 --> 08:03.940 And if you have any question on this use the question and answer section. 08:03.940 --> 08:06.670 And I'm going to get back to you as soon as possible. 08:06.700 --> 08:07.690 Thank you so much. 08:07.690 --> 08:10.930 And I'm going to see you in the next video lecture.
